Question

the sum of six interior angles of a regular octagon is 800 the other two angles are equal find the size of each angle​

Answer 1

An octagon is a polygon with 8 sides and angles. The two equal angles are 140 degrees each

How to calculate the sum of an interior angle of a polygon?

An octagon is a polygon with 8 sides and angles

The formula for calculating the sum of interior angle of a regular polygon is expressed as:

S = (n-2) * 180

If the sum of six interior angles of a regular octagon is 800 the other two angles are equal, then;

800 + 2x = (8-2)*180

800 + 2x = 1080
2x = 1080 - 800
2x = 280
x = 140

The two equal angles are 140 degrees each
