Well this decagon has 10 equal sides so all we have to do is divide 360 by 10 to find the measure of the interior angles. 360/10 = 36 So the interior angles are 36º
I hope this helps

First, simplify the parenthesis. You’ll get:
1/4(4z)+7=-z+1
Then multiply 1/4 by 4z. You’ll get:
z+7=-z+1
Love like terms to the same side. I wanted to have the variable positive on time, so I moved variables to the left and constants to the right. You’ll get:
2z=-6
Divide both sides by 2. You’ll get :
z=-3
