problem

A "slackrope walker" is much like a tightrope walker except that the rope on which he performs is not pulled tight. Paul, a slackrope walker, has a rope tied to two 15 m15\text{ m} high poles which are 14 m14\text{ m} apart. When he is standing on the rope 5 m5\text{ m} away from one of the poles, he is 3 m3\text{ m} above the ground. How long in meters is the rope?

Original LaTeX notation
A "slackrope walker" is much like a tightrope walker except that the rope on which he performs is not pulled tight. Paul, a slackrope walker, has a rope tied to two $15\text{ m}$ high poles which are $14\text{ m}$ apart. When he is standing on the rope $5\text{ m}$ away from one of the poles, he is $3\text{ m}$ above the ground. How long in meters is the rope?
