Question

Find the length of the third side. If necessary, round to the nearest tenth.

Answer 1

The length of the third side is 11.6

Answer 2

11.6

Explanation:

let x = length of the 3rd side

16² = 11² + x² 16 is the hypotenuse of a right triangle

x² = 16² - 11²

x² = 256 - 121 = 135

√x² = x = √135 = 11.6
