Answer:

x ≅ 9.5; y ≅ 15.3

Explanation:

The sine proportion is opposite / hypotenuse while the cosine proportion is adjacent / hypotenuse.

We can find x using sine (as the x is the measure of the opposite side and 18 is the hypotenuse) and let 32 be the reference angle:


sin(32)=(x)/(18)\\ 18*sin(32)=x\\9.538=9.5=x

We can find y using cosine (as y is the measure of the adjacent side and 18 is the hypotenuse) and let 32 be the reference angle:


cos(32)=(y)/(18)\\ 18*cos(32)=y\\15.264=15.3=y

X=9.5
Y=15.3

Explanation: sine is opposite over hypotenuse

Cosine is adjacent over hypotenuse
