Answer 2

Option (B) is correct. Sum of exterior angles is 360.

Given:

A pentagon

To find:

Sum of exterior angles of pentagon.

Solution:

Sum of exterior angles of any polygon is 360°.

First, we will find the sum of interior angles.

=(n-2) X 180

So, sum of interior angles of the pentagon is

=5-2 X 180

=540

Each interior angle=3×180°/5

=108°

In order to find the sum of exterior angles, Interior angle and its neighbouring exterior angle forms a straight line. It can be said-

180-108=72°

In order to find the sum of exterior angles add them-

=72°+72°+72°+72°+72°

=360°

Therefore, sum of exterior angle is 360°.
