Answer
Chapter 2 - Section 2.3 Problem Set: 26 (Answer)
Drawing : Refer to Figure I
$\angle B$ = $41.7^{\circ}$
$c = 4.66$ inches (To three significant digits)
$b = 3.10$ inches (To three significant digits)
Work Step by Step
Chapter 2 - Section 2.3 Problem Set: 26 (Solution)
Drawing : Refer to Figure I
$\angle A$ + $\angle B$ + $90^{\circ}$ = $180^{\circ}$ ($\angle$ sum of $\triangle$)
$48.3^{\circ}$ + $\angle B$ + $90^{\circ}$ = $180^{\circ}$
$\angle B$ = $41.7^{\circ}$
$\sin 48.3^{\circ} = \frac{a}{c}$
$c = \frac{3.48}{\sin 48.3^{\circ}}$
$c = 4.66$ inches (To three significant digits)
$\cos 48.3^{\circ} = \frac{b}{c}$
$b = 4.66 \cdot \cos 48.3^{\circ}$
$b = 3.10$ inches (To three significant digits)
