Answer:

Use the pythagorean theorem.


a^2 + b^2 = c^2

The length of one leg, a is 11, and the length of the hypotenuse, the longest side (or c) is 17. Substitute


11^2 + b^2 = 17^2 \\121 + b^2 = 289\\

Subtract 121 from both sides to isolate B


b^2 + 121 - 121 = 289 - 121\\b^2 = 168

Take the square root of both sides to isolate b


√(b^2) =√(168) \\b = 12.961
