Question

Find the value of x, round to nearest degree

Answer 1

For this problem, you would use sine, which is opposite over hypotenuse, and you're trying to find the value of angle so it's $sin^{-1}$ on calculators, if you're using it. 

x = sin^-1(7/15) 
x = 27.8181...

Your final answer is x = 28.
