The measure of an exterior angle of a regular polygon is x, find the measure of one interior angle then find the number of sides basically like 180 - x =
and then 180 ( n - 2 ) / n = 180 - x
all I need is to know what 180 - x is- if not I need to know what n is so I can solve the rest
Thank

Aswimming pool has an input pump for filling the pool and an output pump for emptying the pool. the input pump can fill the pool in 3 hours, and the output pump can drain the pool in 5 hours. as you go to bed, the pool is full, but a neighbor’s kid turns on the output pump. at midnight, you awake to find the pool half empty. immediately, you turn on the input pump, but you are sleepy and forget to turn off the output pump. at what time will the pool become full?
