Answer 1

So, what's sin of the angle given? What's the ratio of the sides?

Answer 2

You have an angle....the hypotenuse...and you want the side opposite that angle...what trig function uses opposite and hypotenuse?

Answer 3

I THINK: sin15 = x/22
22(sin15) = x
22(0.258819045102521) = x
approximately 5.7 = x
