Find the unknown sides of the right triangle b=25.7cm ,a=25.7 find a and c

To answer this question, you can use pythagorean theorem.

Square A (25.7) and square B (25.7) to find the square of C, which you can then square root to find C.

In this case, C squared is 1320.98. When you square root it, you get an answer of 36.3453. (It goes on as a decimal, but I rounded it up)
