CPM Homework Help : INT2 Problem 12-137

Solve this problem without a calculator:

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

$θ$	$\operatorname{cos}(θ)$	$\operatorname{sin}(θ)$	$\operatorname{tan}(θ)$
$28°$	$0.883$	$0.469$	$0.532$

Hint:

Remember that $\text{sin}(\theta)=\frac{\text{opp.}}{\text{hyp.}}, \text{ cos }(\theta)=\frac{\text{adj.}}{\text{hyp.}}, \text{ and tan }(\theta)=\frac{\text{opp.}}{\text{adj.}}.$

How are $\operatorname{sin(62)}$ and $\operatorname{cos(68)}$ related?
