Question

the sum of the interior angles of a polygon is 10 right angles then the number of sides is

Answer 1

Answer:

7 = no. of sides of the polygon

Step-by-step explanation:

Sum of interior angles = 10*90 = 900

180(n-2) = 900                                            [n= no. of sides]

180n -360 = 900

180n = 900 + 360 = 1260

n = 1260/180 = 7

n = 7 = no. of sides of the polygon

Answer 2

2n-4=10

2n=14

therefore, n =¹⁴/²=7
