Question

find the number of sides in a polygon if the sum of its interior angle is :- 16 right angles

Answer 1

no of side =10

(n-2)*180= 16*90 after solving u will get

n = 10

Answer 2

sum of interior angles = 16 × 90°
=1440°
180(n-2) =1440
(n-2) = 1440/180
n-2 =8
n= 10
therefore it is a decagon
