Answer
Chapter 2 - Section 2.3 Problem Set: 45 (Answer)
Refer to Figure I
$x = 79$ (To the nearest digit)
$h = 40$ (To the nearest digit)
Work Step by Step
Chapter 2 - Section 2.3 Problem Set: 45 (Solution)
Refer to Figure I
In $\triangle$ABC,
$\tan 62^{\circ} = \frac{x}{42}$
$x = 42 \cdot \tan 62^{\circ}$
$x = 79$ (To the nearest digit)
In $\triangle$DAB,
$\tan 27^{\circ} = \frac{h}{x}$
$\tan 27^{\circ} = \frac{h}{79}$
$h = 79 \cdot \tan 27^{\circ}$
$h = 40$ (To the nearest digit)
