Answer:
12
Step-by-step explanation:
The two equations are vertical angle, which would be equal to each other.
Set the equations to equal and solve for x:
5x -10 = 3x +40
Subtract 3x from both sides:
2x -10 = 40
Add 10 to both sides:
2x = 50
Divide both sides by 2:
x = 50 / 2
x = 25
The answer is B. 25
Answer:
3
Step-by-step explanation:
The area of a trapezoid is (a+b)/2 * h
a is the length of the small base which is the one on the top and is 4cm
b is the length of the big base which is the one at the bottom and is 4 + 3 + 3 = 10cm
h is the height which is 7cm
So the area is (4+10)/2 * 7
A= 14/2 * 7
A= 7 * 7
A= 49 cm^2
