Answer 1

Answer: 43.2°

In the given diagram, we are given the hypotenuse and opposite side from the angle x. This means that we need to use the sine ratio. When finding the angle in this triangle, we need to use $sine^{-1}$, not just sine. (This applies for other problems that require you to solve for the angle. The equation should be $sine^{-1}(\frac{5}{7.3} )$. Calculate the equation with your calculator to get 43.2
