Best ResponseYou've already chosen the best response.0We have angle \(63^\text o\), so opposite side is h and hypotenuse side is 13.

Best ResponseYou've already chosen the best response.0Nothing. You are solving for h. \(\sin\theta = \dfrac{Opp}{Hyp}\) You are given that \(\theta = 63^\text o\) and \(Hyp = 13\) You are trying to find height aka opposite side.

Best ResponseYou've already chosen the best response.0Yep. Now you have height. However we need base. We have hypotenuse and opposite side, so we can use Pythagorean Theorem here to find adjacent side.
