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
