Answer
$\angle A= 21.4858^{\circ}$
$b \approx 3330.68 m$
$a \approx 1311.04 m$
Work Step by Step
1. $\angle B = 68.5142^{\circ}$
$c= 3579.42 m$
2. $\angle B +\angle A = 90^{\circ}$
$\angle A = 21.4858^{\circ}$
3. $\sin B = \frac{b}{c}$
$b= 3579.42 \times \sin (68.5142^{\circ}) \approx 3330.68 m$
4. $\cos B = \frac{a}{c}$
$a= 3579.42 \times \cos (68.5142^{\circ}) \approx 1311.04 m$
