An airplane flies directly overhead at 600 mph. 2 minutes later it is seen at an angle of elevation of 22 degrees how far did the plane fly during that time.
what is its elevation

Answer:

tan(22°) = h/20

Step-by-step explanation:

Step 1 in this type of a problem is to draw a picture. That way you can see the triangles and angles and distances and better understand their relationship. 2 minutes = 1/30 hour. So at 600 mph, the plan travels:

distance = rate x time

distance = 600 x (1/30

distance = 20 mi.

The angle of elevation to the plane after 2 minutes is 22°. So we have:

tan(22°) = h/20

where h is the plane's height. Solve for h.

I hope this helps!
