Answer:
7.75
Step-by-step explanation:
7.5+8=15.5
15.5/2=7.75
Set them equal to eachother
Just add to find X
20 + 60 = 80
-------------------------------------
X = 80
To make sure plug it in
80 - 60 = 20
The equation is true
-----------------------------------------------
x = 80 is your answer
Side = root over area
= root over 25 = 5 cm
