Answer:
x = 126
each ( x - 30 ) equals 96 degrees
Step-by-step explanation:
Since a pentagon's angles all equal 540 degrees, you can set up the equation like so:
x - 30 + x - 30 + x - 30 + x + x=540
Combine like terms:
5x - 90 = 540
Add 90 to each side:
5x = 630
Divide each side by 5:
x = 126
Substitute into the equation to solve:
x - 30
126 - 30
96
