Answer:
Step-by-step explanation:
The sum of the exterior angles of any polygon is 360 degrees. So first we need to find the measure of the exterior angle to x.
360 - 144 - 72 = 144
144 and x are supplementary, so they add up to 180. That means that
144 + x = 180 so
x = 36
Choice C is the one you want.
5/3x = ? ; where x = 90
90/1 times 5/3
cross simplification
now it's 30/1 times 5/1 i divided the numerator of the first fraction and the denominator of the second fraction by 3
now it is 5 times 30
so... 5/3 of a 90 degree angle is 150 degrees
