Answer:
Estimate 23.3
Step-by-step explanation:
So here we are going to use the Pythagorean Theorem to find the length of the other side.
The formula for it is; [tex]a^{2}+b^{2} =c^{2}[/tex]
So c squared is always the Hypotenuse which is made up a and b squared added together. The Hypotenuse is the longest side and the is the side that we are looking for.
So, [tex]20^{2}+12^{2} =c^{2}[/tex]
400 + 144 = c^{2}[/tex]
544 = c^{2}[/tex]
c = Estimate 23.3
