Question

Another problem I’m struggling with

Answer 1

Use (n - 2) * 180 to find the sum of the measures of the interior angles of the polygon, where n = number of sides.

This polygon has 9 sides so plug in 9 for n.

(9 - 2) * 180 = 1,260

Divide this by the number of sides, 9.

1,260/9 = 140

Now divide this by 2 because x appears to be half of an interior angle (the radius is bisecting the interior angle).

140/2 = 70

x = 70°

Answer 2

i would say 45 due to if you divide by 8
