What are the values of x and y?

Solution given;

we have

Cos 30=adjacent/hypotenuse

Cos 30=12/x

x=12/cos30

x=8√3

and

Sin 30=opposite/hypotenuse

Sin30=y/x

y=sin30*x

y=sin30*8√3

y=4√3

Option D.

x=8√3 and y=4√3 is a required answer.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
