Answer: 176°
Step-by-step explanation: The formula for finding the measure of each interior angle of a regular polygon is 180(n - 2)/n.
n ⇒ number of sides of the polygon
~substitute
180(90 - 2)/90
180(88)/90
= 176
*Note that you may want to use your
calculator to help you with these problems
This means that the measure of each interior angle of a regular polygon that has 90 sides is 176°.
