#### Answer

$x \approx 82 ft$
$y \approx 98ft$

#### Work Step by Step

1. Use tangent to find x
$\tan 20^{\circ} =\frac{30}{x}$
$x\approx 82 ft$
2. Use tangent of another angle to find y
$\tan 50^{\circ} = \frac{y}{x}$ Calculating this use the exact value of x from the calculator
$y\approx 98 ft$
