Answer:
X = 18
Step-by-step explanation:
This is a regular pentagon, meaning that each side is the same. Now, since we know the perimeter, we can divide that by 5 to find each side's length (x). 90/5 = 18, so the length x of each side is 18.
18cm
You would do 90/5 which is 18. Each side of the pentagon is 18cm.
d
The type of angles of <1 and <5 are corresponding angles
x/2=5+4=9
x=9*2=18
x=18!
