Question

Four angles of a nine sided polygon are 1450 each and the remaining angles are equal. Find the value of each equal angle​

Answer 1

Answer:

We know that, the measure of all angles of a nine sided polygon is 1260°.

Given four angles of a nine sided polygon are 145°.

So the rest angles measure are 1260°-145°

= 1115°

The value of each equal angle is 1115°/5

= 223°
