What are the four types of triangles according to angle measure?
The 4 types of triangle are
Acute triangle
Obtuse Triangle
Right triangle
Equivalent triangle
What are the four types of triangles by angle measurement ?A triangle is said to be equilateral if each of its three sides is the same length. In the well-known Euclidean geometry, an equilateral triangle is also equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others.
A triangle having three acute angles is known as an acute triangle. A triangle having one obtuse angle and two acute angles is known as an obtuse triangle. No Euclidean triangle may contain more than one obtuse angle because in Euclidean geometry, a triangle's angles must add up to 180°.
A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Obtuse-angled triangles or obtuse triangles are triangles with any one of its angles being an obtuse angle or more than 90°. Only 180° is equivalent to the internal angles of an acute triangle.

Is 3x2 a exponential function?
No, 3x2 is not an exponential function. An exponential function is a function in which the variable (x) is in the exponent.
The general form of an exponential function is f(x) = a^x, where a is the base and x is the exponent.
In the case of 3x2, the variable (x) is not in the exponent, it's being multiplied by the coefficient 3. This is a linear function, not an exponential function. The general form of a linear function is f(x) = mx+c, where m is the coefficient and c is the y-intercept.
In summary, 3x2 is not an exponential function. An exponential function is a function in which the variable (x) is in the exponent. The general form of an exponential function is f(x) = a^x, where a is the base and x is the exponent. In the case of 3x2, the variable x is not in the exponent, it's being multiplied by the coefficient 3. This is a linear function, not an exponential function.

The mark of the angles and sides of the triangle indicate that they are congruent.
What is congruence of triangle ?Triangle diagram with side and angle indicators. To demonstrate if two or more sides are congruent, indicator marks are utilized (equal in measure).
Triangle congruence: If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create a similar appearance.
When two angles and the included side of one triangle are equal to two angles and the included side of another triangle, two triangles are said to be congruent. PB = DE. The matching triangle portions are equal since the triangles are congruent.

In the accompanying figure, angle 1 measures 28o and angle 2 measures 11o. What is the measure of angle 3
The measure of angle 3 in the given triangle is 141 degrees.
Angle 1 + Angle 2 + Angle 3 = 180°
So, Angle 3 = 180° - (Angle 1 + Angle 2)
Angle 3 = 180° - (28° + 11°)
Angle 3 = 141°
The sum of the three angles in a triangle is 180 degrees, so to calculate the measure of angle 3, we can subtract the measures of angles 1 and 2 from 180 degrees. In this case, angle 1 measures 28 degrees and angle 2 measures 11 degrees, so the measure of angle 3 is 180 degrees minus (28 degrees + 11 degrees), or 141 degrees.
The measure of angle 3 in the given triangle is 141 degrees.

Gong rented a truck for one day. There wa a bae fee of $19. 95, and there wa an additional charge of 71 cent for each mile driven. Hong had to pay $125. 74 when he returned the truck. For how many mile did he drive the truck?
Gong must have driven the truck for 149 miles as per the given problem.
Let’s discuss the problem in detail.
In addition to the base rate of $19.95, there was an extra fee of 71 cents for every mile driven. When Gong returned the truck, he was required to pay $125.74.
Now we have to calculate how far did he drive the truck before stopping.
First, let’s convert all dollars into cents.
Base fee = 1995 cents.
71 cents for each mile.
Total Gong gave 12574 cents.
Assume Gong drive for x miles.
Therefore, 12574 = 1995 + 71 * x
= 71x = 12574 - 1995
= 71x = 10579
= x = 10579/71 = 149 miles.
Hence, Gong drove the truck for 149 miles before stopping.

What is error in math?Error in math is an incorrect answer to a mathematical equation or problem. It can be caused by a variety of factors, such as inaccurate calculations, misreading instructions, or not understanding the problem. Error in math can be frustrating and can lead to poor grades, but it can also be an opportunity for learning and growth. With the proper guidance and understanding, students can learn from their mistakes and become better mathematicians.
The scatterplot would likely show a negative correlation, with the number of errors decreasing as the number of hours studied increases. This indicates that as students study more, their performance on multiplication tests improves. It could also show an outlier or two, which could indicate that some students are able to learn multiplication facts more quickly than others.

How do you dilate a triangle with a scale factor of 1 2?
If the scale factor is 1/2, then every coordinate point of the original triangle is multiplied by the scale factor 1/2. Dilation with scale factor 1/2, then multiply by 1/2.
How do construct a dilation of 1 2?To dilate the figure by a factor of 2, I will multiply the x-value of each point by 2. I plotted all the new points to find the new triangle. To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2.If the scale factor is a fraction, the shape will be smaller. This is called reduction. Therefore, a 1/2 scaling factor means that the new shape is half of the original shapeThe scale factor = Smaller figure dimensions ÷ Larger figure dimensions = 20/40 = 1/2. Therefore, the scale factor used to create the smaller polygon is 1/2. Example 3. A triangle was increased by a scale factor of 2 resulting in the new dimensions as 6 units by 10 units by 12 units.To learn more about construct a dilation refers to:

How to use the Law of Cosines?Measure or determine the lengths of all three sides of the triangle (a, b, and c). Let's say a = 5, b = 6, and c = 7.
Substitute the side lengths into the formula above and solve for cos A. cos A = (6^2 + 7^2 - 5^2) / (267) = 0.6
Use the inverse cosine function to find the measure of angle A in degrees or radians. In this case, A = 60 degrees.

What is the value of K if X 1 is the factor of 4x³ 3x² 4x K?
The value of k is -3, if x - 1 is a factor of 4x³ + 3x² − 4x + k.
A polynomial factor is a polynomial that divides another polynomial exactly, with no remainder.
For example, if we have a polynomial P(x) = 4x³ + 3x² − 4x + k, and we have a polynomial factor F(x) = x - 1, we can say that P(x) is divisible by F(x) with no remainder.
In general, a polynomial of degree n has n roots (or zeroes) and the factorization of polynomial can be expressed as a product of its roots and its corresponding multiplicity.
To find the value of k, set x = 1 in the equation 4x³ + 3x² − 4x + k and solve for k that will make the equation equal to zero..
So when x = 1, we have:
4x³ + 3x² − 4x + k = 0
4(1)³ + 3(1)² − 4(1) + k = 0
4 + 3 - 4 + k = 0
k = -3
Hence, if x - 1 is a factor of 4x³ + 3x² − 4x + k, then k is equal to -3.
