Question

find the measure of one interior angle in each polygon. Round your answer to the nearest tenth if Necessary.

Answer 1

An interior angle of a polygon is an angle formed inside the two adjacent sides. In our case, an interior angle is the angle in red color:

In our case, there are 8 sides so our polygon is an octagon. So, the size of each interio angle is given by

$\frac{(8-2)\times180}{8}=\frac{6\times180}{8}=135$

Therefore, the answer is 135 degrees:
