Ineed asap each exterior angle angle of a polygon measures 45 degrees.1. find the number of sides the polygon has name the polygon.2. find the sum of the measures of the polygons interior angles.

Alright, lets get started.

If the polygon measures 45 degree exterior angle and we are asked to find number of sides, there is a formula for that.

= value of exterior angle

Where n is number of sides of ploygon

Multiplying n into both sides

Now divide 45 in both sides

n = 8

Means number of sides of polygon is 8, hence its Octagon. Answer

Now we have given 45 exterior angle hence interior angle would be

180 - 45 = 135°

So, sum of all interior angles would be = number of sides * interior angle

sum of all interior angles would be =

Hence sum of all interior angles would be 1080°. Answer

Hope it will help :)

you probably already have the answer but anyways it's b. 15.0
