Cade and tyce both tried to find the missing side of the right triangle.
a right triangle is shown. the legs are labeled 6 and 9. a right angle is labeled in between them.

cade's work tyce's work
a2 + b2 = c2 a2 + b2 = c2
62 + b2 = 92 62 + 92 = c2
36 + b2 = 81 36 + 81 = c2
b2 = 45 117 = c2
square root b squared equals square root 45. square root 117 equals c squared.
b ≈ 6.71 10.82 ≈ c

is either of them correct? explain your reasoning.
