from the top of a 120-foot high tower an air traffic controller observes an airplane on the runway at an angle of depression of
Crazy boy [7]
Data:
h (<span>Tower height) = 120 ft
d (</span><span>Distance from the base of the tower to the airplane) = ?
</span>\alpha (<span>Angle formed from observation of the tower to the airplane)=19º

Data: tg 19º </span>≈ 0.34
<span>
Note: </span><span>The angle formed is tangent to the height of the tower and the distance from the base of the tower to the airplane.

</span><span>Formula:
</span>tg \alpha =  \frac{opposite\:leg}{adjacent\:leg}
<span>
Solving:
</span>tg \alpha = \frac{opposite\:leg}{adjacent\:leg}
tg 19^0 = \frac{h}{d}
tg 19^0 = \frac{120}{d}
0.34 =  \frac{120}{d}
0.34*d = 120
0.34d = 120
d =  \frac{120}{0.34}
\boxed{\boed{d \approx 352.9\:ft}}\end{array}}\qquad\quad\checkmark

Answer:
<span>Distance from the base of the tower to the airplane is aproximately  352.9 ft</span>
