Answer:
x = 24
Step-by-step explanation:
We can tell by two ways: We already know the value of one of the angles; 66 degrees. We can tell the value of the other one, because it has the right angle symbol, meaning it's 90 degrees. Remember that every triangle's degrees always add up to 180. We can find x by adding 90 and 66 together, which results in 156. Subtract 156 from 180 and you get 24. Therefore, the value of x is 24 degrees.
Answer:
24 degrees
Step-by-step explanation:
The total of a triangle is 180 degrees and a right angle is 90 degrees ( you can tell it's a right angle if it forms the shape of a straight capital "L" or if it has the square in that corner).
So to simplify this , add 90 and 66 which equals 156.
Now we subtract 156 from 180 ----> 180 - 156 = 24
So 24 degrees is your answer.

Find the hypotenuse of a right triangle that has a 13cm leg and a height of 7cm
Answers
Answer:
14.76 cm
Step-by-step explanation:
Use the pythagorean theorem:
a² + b² = c²
Plug in the side lengths and solve for c:
7² + 13² = c²
49 + 169 = c²
218 = c²
14.76 = c
So, the hypotenuse is approximately 14.76 cm

The combined area of a square and a rectangle is 33 square meters. The width of the rectangle is 1 meter more than the length of one side of the square and the length of the rectangle is 3 meters more
than its width.
a) Calculate the dimensions of the rectangle and its perimeter
b) Calculate the dimensions of the square.
Answers
Answer:
Step-by-step explanation:
Square is x meters on each side.
Area of square = x²
Width of rectangle = x+1
Length of rectangle = x+4
Area of rectangle = (x+1)(x+4) = x²+5x+4
Combined area = 2x²+5x+4 = 33
2x²+5x-29 = 0
x = [-5+√(5²-4(2)(-29))]/[2(2)] = [-5 +√257]/4
[AB] is a diameter of center C(O, 3cm). M is a point on (C) such that MA=MB. D is the symmetric of A with respect to M.
What is the nature of triangle AMB? Justify.
Answers
Answer:
Isosceles right triangle.
Step-by-step explanation:
From the given triangle ABM,
AM ≅ MB [Given]
∠AMB is an angle subtended by the diameter AB.
By theorem, angle subtended by a diameter is always 90°.
m∠AMB = 90°
So the given triangle is a right triangle with two equal sides AM and MB.
Therefore, ΔAMB is an isosceles right triangle.
10. Tim bought two copies of the same hardcover book and three
copies of the same paperback book cost $118. Sally bought three of
the hardcover books and two of the paperback books for $137. Find
the cost for each type of book.
Answers
Answer:
Let hardcover book be x
Let paperback book be y
2x+3y=$118....Equation 1
3x+2y=$137.... Equation 2
Solve for x and y using simultaneous equation
Using elimination method
2x+3y=118......×3
3x+2y=137......×2
6x+9y=354
6x+4y=274
9y-4y=80
5y=80
y=80÷5=16
substituting y=16 into equation 1
2x+3(16)=118
2x+48=118
2x=70
x=70÷2=35
Therefore hardcover costs $35 each
paperback cover costs $16 each

Find the measure of the angle
Answers
Answer:
27
Step-by-step explanation:
The triangle shown is an isoceles triangle. This means that there are two congruent base angles and a vertex angle. In this case, angle X and angle Y are the base angles, so we can set up an equation to first find the value of t.
5t - 13 = 3t + 3
2t - 13 = 3 (Subtract 3t from both sides)
2t = 16 (Add 13 to both sides)
t = 8 (Divide both sides by 2)
Now that we have the value of t, we can plug it back in to the expression for angle X to find its measure.
5(8) - 13
40 - 13
27
So, the measure of angle X is 27

An ice cream shop sells 700 cones per day at a price of $4.50. A survey lets the owner know
that for every decrease in price of $0.50, they will be able to sell 100 extra cones. Write an
equation for the Revenue, R, which can be used to determine how much the owners should
charge in order to maximize their revenue.
Answers
Answer:
R(x) = (4.50 – 0.50x)(700 + 100x)
___________________________
R(x) is in factored form
Where x is each decrease in the price.
____________________________
Explanation:
R(x) is in the form ax² + bx + c.
This is where the equation is distributed and simplified [Standard form]
The maximum revenue is represented by
R(-b/2a), where the vertex of this relationship is, at x = -b/2a.
Revenue = (Price)(Quantity)
____________________________
R(x) = (4.50 – 0.50x)(700 + 100x) →
-50x² + 100x + 3150 [ax² + bx + c].
x = -b/2a
x = -(100)/2(-50)
x = -100 / -100
x = 100 / 100
x = 1
Therefore R(1) or where the price is decreased by a factor of 1 is the maximum revenue.
R(2) = -50(1)² + 100(1) + 3150
R(2) = -50(1) + 100 + 3150
R(2) = -50 + 100 + 3150
R(2) = 3200.
_______________________________
Thus the best revenue ($3,200) is obtained by decreasing the price once (Price of 4$), with 800 cones.

46 + 4x - 2 + 9x + 6 + 8x - 5 = 360
21x + 45 = 360
21x = 315
x = 15
Let me know if you have questions.
Answer:
15
Step-by-step explanation:
The sum of angles around a point is added up to 360°.
Accordingly,
4x - 2 + 9x + 6 + 8x - 5 + 46 = 360
Combine like terms.
21x + 45 = 360
Subtract 45 from both sides.
21x = 360 - 45
21x = 315
x = 15
Tom spent half of his allowance going to the movies. He washed the family car and earned 7 dollars. What is his weekly allowance if he ended with 15 dollars?
Answers
Answer:
Tom's weekly allowance is $16.
Step-by-step explanation:
With the information provided, first you have to subtract the amount he earned washing the family car from the total amount he had to determine the amount he had left from his allowance after going to the movies:
$15-$7=$8
Now, since the statement indicates that tom spent half of his allowance going to the movies, this means that the $8 represents the amount left after going to the movies and it is half of his allowance. So, you have to multiply this amount by 2 to find his weekly allowance:
$8*2=$16
According to this,the answer is that Tom's weekly allowance is $16.
