Question

A regular polygon has an interior angle of 144
How many sides does it have​

Answer 1

Step-by-step explanation:

A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440° .

Answer 2

Answer:

Since the interior angle is 144 degree, each exterior angle is 180 - 144 = 36 degrees.For any convex polygon (in particularly, for any regular polygon) the sum of exterior angles is 360 degrees.Hence, the number of sides = the number of vertices = 360%2F36 = 10.Answer. Your polygon is decagon with 10 sides (vertices).
