Question

Find the length of each missing side. Give your answer in the simplest radical form.

Answer 1

Answer:

$m = n = 9\sqrt 2$

Step-by-step explanation:

Given is a 45° 45° 90° triangle.

So,

$m = \frac{1}{ \sqrt{2} } \times 18 = \frac{1}{2} \times 18 \sqrt{2} = 9 \sqrt{2} \\ \\ n = \frac{1}{ \sqrt{2} } \times 18 = \frac{1}{2} \times 18 \sqrt{2} = 9 \sqrt{2}$
