Step-by-step explanation

We are asked to find the value of v and w

To do so, we will make use of trigonometric identities

Let us get the value of v first


\begin{gathered} sin65^0=(opposite)/(hypotenuse)=(v)/(15) \\ \\ sin65=(v)/(15) \end{gathered}

cross multiply to get v


\begin{gathered} v=15* sin65 \\ v=13.6 \end{gathered}

The value of v is 13.6

Next, we will get w


\begin{gathered} sin\text{ w=}(opposite)/(hypotenuse)=(v)/(21)=(13.6)/(21) \\ \\ sin\text{ w=}(13.6)/(21) \\ \\ sin\text{ w=0.6476} \\ \\ w=\sin^(-1)(0.6476) \\ \\ w=40.4^0 \end{gathered}

The value of w is 40.4 degrees
