P/90 = 4/18
18P = 90*4 [cross-multiplication]
P = 360/18
P = 20
So, answer is P equals to 20
Answer: 172.8°
Step-by-step explanation:
For a regular polynomial of N sides, the sum of all interior angles must be equal to:
Sum = (N - 2)*180°.
In this case we have N = 50
Then:
Sum = (50 - 2)*180° = 48*180°
Now, if all the 50 interior angles have the same measure, then the measure of each one will be equal to the quotient between the sum and the number of sides, this is:
Sum/50 = (48/50)*180° = 172.8°
Then the interior angles of a regular polygon of 50 sides is 172.8°

Answer:
$23.69 an hour
Step-by-step explanation:
Assuming that its two parents working roughly 160 hours a month (of a full time job) they would need to be making at least 23.69 an hour to meet your annual requirement (rough estimate hopefully it helps you get on track though)
