Question

Solve for x

What is the measure of the very top angle? (4x-8)
What is the measure of the side angle? (3x-5)

Answer 1

Angle 4x-8=132 degrees
Angle 3x-5= 100 degrees
A pentagons interior angles all added up together is 540 degrees.
91+125+92=308
The two angles we do not know what are both add up to (540-308) 232 degrees.
So 4x-8+3x-5=232
7x=232+8+5
7x=245
X=245/7=35
X=35
Now we can plug it in the equation.
4x35-8=132
3x35-5=100
