Question

The sum of a regular pentagon’s internal angles is 1440 degrees. Find the number of degrees in each angle in the polygon.

Answer 1

A pentagon has five (5) internal angles.

1/5  of  1440°  is  288° .

But the sum of any pentagon's internal angles is 540°, not  1440°.

Answer 2

easy peasy
pentagon
gon=sides
penta=5
5 sides
therefor 5 internal angles
regular pentagon's angles are all equal
therefor
if a=measure of each angle
5a=total=1440
solve for a
5a=1440
dividie btoh sides by 5
a=288

288 degrees
