Answer:
Step-by-step explanation:
use the below to remember how to use trig functions ( copy this to your computer for use later )
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
We can use TOA to find AC
Tan(31) = Opp / 9
9* Tan(31) = Opp ( Opp = AC)
5.407745571 = AC
