Question

Find the sum of the interior angle measures of a regular polygon with 13 sides

Answer 1

1,980

Explanation:

using the formula

(n – 2) × 180°

= (13 – 2) × 180°

= 11 × 180

= 1,980

if we were asked to find the interior angle

we will use this formula

`interior \: angle \: of \: a \: polygon = (sum \: of \: interior \: angle)/(number \: of \: sides)`

= 1,980/13

= 152.3°

i hope all this helped
