McKenzie and Cara both tried to find the missing side of the right triangle.
A right triangle is shown. One leg is labeled 5 and the other is labeled 13. A right angles is labeled in between the legs.

McKenzie's Work Cara's Work
a^2 + b^2 = c^2 a^2 + b^2 = c^2
5^2 + 13^2 = c^2 5^2 + b^2 = 132
25 + 169 = c^2 2^5 + b^2 = 169
194 = c^2 b^2 = 144
(Square root 194 equals square root c squared. Square root b squared equals square root 144. This is for Cara's work)
13.93 ≈ c b ≈ 12

Is either of them correct? Explain your reasoning.
