Using trigonometric relations we can see that:

x = 34.64

y = 20

Let's find the value of x.

We can see that we have a right triangle, notice that x is the opposite cathetus of the given angle.

Then we can use the trigonometric relation:

sin(angle) = (opposite cathetus)/hypotenuse

Then:

sin(60°) = x/40

Solving for x:

x = 40*sin(60°) = 34.64

Let's find y.

y is the adjacent cathetus, so we use the cosine relation:

cos(60°) = y/40

y = cos(60°)*40

y = 20
