9-109.

Multiple Choice: Solve this problem without a calculator:

Examine the triangle below. Find the approximate value of $x$. Use the values in the trigonometric table below as needed.

 $θ$ $cosθ$ $sinθ$ $tanθ$ $28°$ $0.883$ $0.469$ $0.532$ $62°$ $0.469$ $0.883$ $1.881$
1. $4.69$

1. $5.32$

1. $8.83$

1. $18.81$

1. None of these

(c) because $\sin\left(62^{\circ}\right)=\frac{x}{10}$, so $0.883=\frac{x}{10}$. Isolate $x$, so $x\approx8.83$.
