Asked by Bailey

A balloon is flying west of two trigonometry students who are 7 miles apart. The angles of elevation of the two students to the balloon are 15 and 28 degrees. Approximate how high the balloon is flying.
Answered by Steve
As usual, draw a diagram. It is clear that if the nearer student is x away from the spot under the balloon, then

h/x = tan 28°
h/(x+7) = tan 15°

Eliminate x and you have

h/tan28° = h/tan15° - 7
Now just solve for h

If the set is 25ft, and angle A is 22.5 degrees, the travel is how many ft?
