CaHeK987 [17]
4/3 = 1/x.....4 lbs potatoes to $3 = 1 lb of potatoes to $x
cross multiply
(4)(x) = (3)(1)
4x = 3
x = 3/4
x = 0.75....so 1 lb of potatoes cost 75 cents

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.

\frac{360}{n} = value of exterior angle

Where n is number of sides of ploygon

\frac{360}{n}  = 45

Multiplying n into both sides

\frac{360}{n} * n = 45 n

360 = 45 n

Now divide 45 in both sides

\frac{360}{45}  = \frac{45n}{n}  = n = 8

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 = 8 * 135 = 1080

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

Hope it will help :)
