Answer:
<u><em>Question 1:</em></u>
<em>The sum of interior angles of a polygon can be found by the following formula:</em>
(n-2) × 180
<em><u>Where n is the no. of sides</u></em>
A pentagon has 5 sides
So,
= (5-2) × 180
= (3) × 180
= 540 degrees
<u><em>Question 2:</em></u>
Since The sum of interior angles of a regular octagon is 1080 and the total interior angle are 8
So, Measure of interior angle =
Measure of interior angle = 135 degrees
<u><em>Question 3:</em></u>
<em><u>Since, one interior angle in a hexagon measures 120 degrees.</u></em>
So,
<em>The interior angle should be subtracted by 180 to get the exterior angle.</em>
Exterior angle = 180-120
Exterior Angle = 60 degrees
