Find the missing side

Answer:
-2.44
Step-by-step explanation:
Is a right angle triangle
We apply SOHCAHTOA
SOH is sin=Opposite divided by Hypotenuse
CAH is cos=Adjacent divided by Hypotenuse
TOA is tan=Opposite divided by Adjacent
so in this case,cos is the right thing to use
Therefore,x=adjacent
15=Hypotenuse
angle=52°
Cos(52)=x÷15
making x the subject,
x=15cos(52)
x= -2.44
