Question

Need help do not understand. Trig confused on what formula I should use?

Answer 1

In this triangle, you have

`\sin35^\circ=\frac{12}x\implies x=(12)/(\sin35^\circ)\approx20.9`

(Think sine = opposite/hypotenuse. The leg opposite the labeled angle has length 12, and the hypotenuse is
`x`.)
