Answer:
see below
Step-by-step explanation:
to express x as a function of y we need to form this

and to express y as a function of x

so we work
1)

2)

25320+11310=36,630 or 12,430+24,200=36,630
Data:
h (<span>Tower height) = 120 ft
d (</span><span>Distance from the base of the tower to the airplane) = ?
</span>

(<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>
