Answer:
x = 67.5°
Step-by-step explanation:
A circle's angles add up to 360°
So,
x+3x+90 = 360
4x+90 = 360
4x = 360-90
4x = 270
Dividing both sides by 4
x = 67.5°
Answer: 75
Step-by-step explanation:
The area formula for a trapzoid is area= 1/2 (a+b) h
In this equasion, the substitution would be area=1/2 (10+15) 6
Following PEMDAS, enter the numbers within the parenthases (10+15)
Divide the 25 in half, then multiply by 6. This comes out to 75.
You have to use this equation the a=5, h=4 and b=9 and you should get the answer of 28
