If you make a sketch, a trig relation should suggest itself.Suppose you live about 5.1 miles away from a tower.
From your home, you see a plane directly above the tower.
Your angle of elevation from the plane is 21º.
What is the plane's altitude?Code:P * | * | * a | * | * | 21° * T * - - - - - - - - - - - * H 5.1
Your house is at ; the tower is at
The plane is at
Relative to , we have: .
