Answer:
Interior angle
176 degrees
Exterior
4 degrees
Step-by-step explanation:
Exterior angle
For any polygon, the measure of the total exterior angle is 360
To get the individual exterior angle, we divide the total by n, which is the number of sides, 90 in this case
We have this as;
360/90 = 4
Interior
To get the measure of each interior angle, we use the formula below;
[(n-2)180]/n
n in this case is 90
So we have
[(90-2)180]/90
= (88 * 180)/90
= 2 * 88 = 176
