A guy wire of length 50 feet is attached to the ground and to the top of an antenna. The height of the antenna is 10 feet larger than the distance from the base of the antenna to the point where the guy wire is attached to the ground. What is the height of the antenna?

using pythagoras theorem, x^2 + (x+10)^2 = 50^2. Solving the resulting quadratic eqn. gives x = 30, 40. Since the antenna's height is the one required, it must be 40 feet.

This is an elementary algebra problem, solvable by using the Pythagorean relationship. The answer, by inspection, is 40 feet.
