The measure of the missing side of the right triangle are as follows;

adjacent side = 5√2

hypotenuse =  10

<h3 /><h3>How to find the side of a right triangle?</h3>

A right angle triangle has one of its angles as 90 degrees.

Therefore,

using trigonometric ratios,

tan 45 = opposite / adjacent

tan 45 = 5√2 / a

adjacent side = 5√2 / 1

Therefore,

adjacent side = 5√2

sin 45 = opposite / hypotenuse

hypotenuse = 5√2 / √2 / 2

hypotenuse =  5√2 × 2 / √2

hypotenuse =  10
