Answer:

If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .

Consider the sum of the measures of the exterior angles for an n -gon.

N=180n−180(n−2)

Distribute 180 .

N=180n−180n+360 =360.

Riya had spent 1/4 of her money on chocolates and 1/8 on pizza and has $40 left how much money did she have in the beggining
salantis [7]

Answer:

$64

Step-by-step explanation:

Remaining money = 1 - (1/4 + 1/8)

Remaining Money = 1 - 3/8

Remaining Money = 5/8

$40 = 5/8 of Starting amount

Starting amount = $40 * 8/5

Starting amount = $64
