Question

find the sum of all interior angle in 10 sided polygon​

Answer 1

Answer:

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

${\huge{\mathcal{\pink{ANSWER}}}}$

sum of all Interior angles =

2(n-2) ×90°

here, n = 10

sum =

2×(10-2)×90°

2×8×90°
