Question

Find the value of x.

Answer 1

Hey there :)

Here we need to use Trigonometry!

The given angle is 61°
The opposite to the angle is 22 
So x is the adjacent

The trigonometric ratio that uses opposite and adjacent is tan
( I have uploaded a picture to help you )


tan α = $\frac{opposite}{adjacent}$
tan 61 = $\frac{22}{adj}$
adj = $\frac{22}{tan(61)}$
adj ≈ 12.19 ≈ 12

x = 12
