To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon. (which is the same as the number of sides). There are 108° in each interior angle of a regular pentagon. This process can be generalized into a formula for finding each interior angle of a REGULAR polygon ...
Answer:
F= (9C+160)/5
Step-by-step explanation:
C=5(F-32)/9
make F the subject of the formula= isolate F
5(F-32)=9C
5F-160=9C
5F=9C+160
F= (9C+160)/5
check: a, b, c are all positive integers (a=9, b=160, c=5)
