Charlie is at a small airfield watching for the approach of a small plane with engine trouble. He sees the plane at an angle of
Lera25 [3.4K]
Check the picture.

Let the given points represent the following:

F : Charlie's feet
E: Charlie's eyes
P: location of the plane
G: the foot of the perpendicular drawn from P to the ground
A: a point on PG, such that |GA|=|FE|=5.2 feet.

Clearly EAP is a right triangle, with m(AEP)=32°, side PA=1,700-5.2=1694.8 feet.

<span>the ground distance from Charlie to the plane is |FG|=|EA|

from right angle trigonometry, we know that:

</span>tan32= \frac{PA}{AE}
<span>
</span>0.625= \frac{1694.8}{AE}
<span>
</span>AE= \frac{1694.8}{0.625}=2711.68 feet
<span>

Answer: 2711.68 feet</span>
