Question

What is the answer of this QUESTION ​

Answer 1

Step-by-step explanation:

i). 13 sides

Maths keeps one mentally active. (2n - 4) = 1980/90 = 22. So 2n = 22 + 4 = 26, thus n = 13. Therefore the polygon has 13 sides.

ii). 20 sides

Maths keeps one mentally active. Obviously, 3240 deg is the sum in the interior angles of a regular polygon (of n sides). n = 20 sides.

Answer 2

Answer:

1) 13. 2)20

Step-by-step explanation:

1)(2n-4)=1980/90 = 22. that 2n = 22+4= 13

2) 3240.is same angle of polygon
