Your answer would be 8n+10 because you have to combine like terms. you would do 3n+3n+n+n which gives you the 8n and then you would do -5+-5+10+10 which gives you the 10 and when you put it all together, you get 8n+10.

Find the value of x.

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
