Find m∠1. Then classify the triangle by its angles.
The triangle can be classified by its angles as
A. Right
B. Obtuse
C. Equiangular
D. Acute
The measure of angle 1 from the given triangle is 81°.
In the given triangle, the measure of two angles are 78° and 31°.
What is angle sum property of a triangle?Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
From the angle sum property of triangle,
78°+31°+m∠1=180°
⇒ 109°+m∠1=180°
⇒ m∠1=180°-109°
⇒ m∠1=81°
Therefore, the measure of angle 1 from the given triangle is 81°.

Write an equivalent expression to (-0.25x - 3) - (2.5x + 1.7) using the fewest possible terms.
Answer: -2.75*x - 4.7
Step-by-step explanation:
In the equation we have only one variable, this means that the minimum possible number of terms will be two, one term with x, and one term without x.
We can start with the equation:
(-0.25x - 3) - (2.5x + 1.7)
Now, let's rewrite this as:
-0.25x - 3 - 2.5x - 1.7
(-0.25*x - 2.5*x) + (-3 - 1.7)
Solving the parentheses we get:
-2.75*x - 4.7
That is the equivalent expression that has the fewest possible terms

subtract 6 from x and subtract 3 from y
im gonna chak another just in case
3rd one
(10,10) to (4,7)
same rule
so for the second one they give us (-4,7)
to get this we subtracted 6 from x and 3 from y from original so
lets work backwards
add 6 from x and add 3 from y
(-4,7)+(6,3)
answer(2,10)
now D'
subtract 6 from x and 3 from y

Answer:
N165.53°E
Step-by-step explanation:
Given the following vector points
Vx = -43.0units
Vy = 11.1 units
The direction of the vector is expressed using the formula:
θ = tan^-1(Vy/Vx)
θ = tan^-1(11.1/-43.0)
θ = tan^-1(0.2581)
θ = -14.47°
Since tan is negative in the second quadrant, hence the required direction will be θ = 180-14.47
θ = 165.53°
Hence the direction is N165.53°E

At 5 p.M., the temperatures recorded at two weather stations in Antarctica are -6 degrees and 2 degrees. The temperature changes at the same constant rate, x degrees per hour, throughout the night at both locations. The temperature at the first station 3 hours after this recording is the same as the temperature at the second station 4 hours after this recording.
Answer:
- 8° per hour
Step-by-step explanation:
Given that:
Station A = - 6°
Station B = 2°
Rate of temperature change = x° / hour ; which is the same at both stations
Temperature at station A 3 hours after the recording is the same as the temperature in station B 4 hours after the recording ;
Temperature change in Station A:
-6 + 3x
Temperature change in station B:
2 + 4x
Temperature change in A = temperature change in B
-6 + 3x = 2 + 4x
Collect like terms
3x - 4x = 2 + 6
- x = 8
x = - 8
Hence, the rate of temperature change x in both stations is - 8° per hour

The juniors and seniors at a high school are ordering class shirts. The amounts ordered in each size are shown in the two-way frequency table below.
Small Medium Large X-Large Total
Juniors 65 84 68 23 240
Seniors 51 62 79 28 220
Total 116 146 147 51 460
Which statement is true about the information represented in the table?
A The percentage of Seniors who ordered a large shirt is greater than the percentage of students who ordered a large shirt who are also in the Senior class.
B The percentage of Seniors who ordered a small shirt is the same as the percentage of students who ordered a small shirt who are also in the Senior class.
C The percentage of Juniors who ordered a medium shirt is greater than the percentage of students who ordered a medium shirt who are also in the Junior class.
D The percentage of Juniors who ordered a medium shirt is less than the percentage of students who ordered a medium shirt who are also in the Junior class.
Answer:
it b
Step-by-step explanation:
To determine which statement is true, we need to calculate the percentages for each option and compare them and option c is correct.
Option A: The percentage of Seniors who ordered a large shirt is greater than the percentage of students who ordered a large shirt and are also in the Senior class. To calculate the percentage of Seniors who ordered a large shirt, we divide the number of Seniors who ordered a large shirt by the total number of Seniors:
Percentage of Seniors who ordered a large shirt =[tex](79 / 220) * 100 = 35.91[/tex]% To calculate the percentage of students who ordered a large shirt and are also in the Senior class, we divide the number of Seniors who ordered a large shirt by the total number of students who ordered a large shirt: Percentage of students who ordered a large shirt and are also in the Senior class [tex]= (79 / 147) * 100 = 53.74[/tex]% Since the percentage of students who ordered a large shirt and are also in the Senior class is greater than the percentage of Seniors who ordered a large shirt, statement A is false.
Similarly, we can calculate the percentages for the other options: Option B: The percentage of Seniors who ordered a small shirt is the same as the percentage of students who ordered a small shirt and are also in the Senior class. Percentage of Seniors who ordered a small shirt [tex]= (51 / 220) * 100 = 23.18[/tex]% Percentage of students who ordered a small shirt and are also in the Senior class [tex]= (51 / 116) * 100 = 43.97[/tex] % Since the percentages are not the same, statement B is false.
Option C: The percentage of Juniors who ordered a medium shirt is greater than the percentage of students who ordered a medium shirt and are also in the Junior class. Percentage of Juniors who ordered a medium shirt [tex]= (84 / 240) * 100 = 35[/tex]% Percentage of students who ordered a medium shirt and are also in the Junior class [tex]= (84 / 146) * 100 = 57.53[/tex]% Since the percentage of students who ordered a medium shirt and are also in the Junior class is greater than the percentage of Juniors who ordered a medium shirt, statement C is true.
Hence the correct option is C.
