Find the value of x & y
y
12
30

x = 12 = 8

y = 12 = 4

Let me know if you need some help simplifying the expressions or o the trig side of things

Step-by-step explanation:

I'm not sure if this is full out trig or recognizing special triangles, specifically 30-60-90 triangles.  Of course since one angle is 30 degrees and the other is 90 degrees this is a 30-60-90 triangle.

with 30-60-90 tringles  the basic guide is as follows.

The three legs will be referred to as the hypotenuse, short leg and long leg.  I will use H, S and L.  

H = 2S = L

S = .5H = L

L = H = S

If this is trig just break out the unit circle and SOH CAH TOA

So x is the hypotenuse, and y is the short leg and we know the long leg is 12, so we can use that.

to find the hypotenuse knowing the long leg we use H = L and to find the short leg with the long leg you use S = L.  now just plug in 12 for L
