Question

The sum of interior angles of a polygon with (2n - 3) sides is equal to 62 right angles. Find the value of n.

Answer 1

Thus the value of n is 18

Step-by-step explanation:

Given ,

sum = 62 right angles and N = 2n-3

sum of 62 right angles = 62*90

Here is our equation:

Sum = (N-2) x 180°

62×90 = (2n-3 - 2)180

$2n - 5 = \frac{62 \times 90}{180}$

2n - 5 = 62/2

2n -5 = 31

2n = 31 + 5

n = 36/2

n = 18
