What is the second step in finding the missing side length of the right triangle?

•  $8^2+15^2\ =\ 289$ Now take square root of 289 to find the length of the hypotenuse.

•  $8^2+15^2=289$  You are done. The missing side is 289.

•  $15-8=7$ You are done.  The missing side is 7.

•  $15^2-8^2=161$  Now take square root of 161 to find the length of the hypotenuse.
