Question

Find the length of the third side. If necessary, write in simplest radical form.

Answer 1

`\text{Apply Pythagorean theorem,}\\\\~~~~~~~~\text{Hypotenuse}^2=\text{Base}^2 + \text{Perpendicular}^2\\\\\implies 9^2 = \text{Base}^2 + \left(2√(14) \right)^2\\\\\implies 81 = \text{Base}^2 + 56\\\\\implies \text{Base}^2 = 81-56\\\\\implies \text{Base}^2 = 25\\\\\implies \text{Base} = √(25)\\\\\implies \text{Base} = 5\\\\\text{The length of the third side is 5 units.}`
