Answer:
39.9
Step-by-step explanation:
A good trick to remember is SOH CAH TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we're given an angle and the opposite side, and we want to find the adjacent side. So we need to use tangent.
tan 31° = 24 / x
x = 24 / tan 31°
x ≈ 39.9
Hey there!
First, let's multiply each side of the equation by 3 to get rid of the fraction 
.
9 + 2x = 
Next we can multiply each side of the equation by 5 to get rid of the fraction .
45 + 10x = 6
There's your answer!
Hope this helps!
