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 m high poles which are 14 m apart. When he is standing on the rope 5m away from one of the poles, he is 3m above the ground. How long in meters is the rope?
Two right triangles with legs 5 and 12 and 9 and 12 Use pythagorean theorem to calculate and add the hypotenuses together.....
Triangle on the left hypotenuse = sqrt [ 5^2 + (15 - 3)^2 ] = sqrt [ 5^2 + 12^2 ] =
sqrt [ 25 + 144 ] = sqrt [ 169 ] = 13 ft
Triangle on the right hypenuse = sqrt [ (14 - 5)^2 + (15 -3)^2 ] sqrt [ 9^2 + 12^2 ] =
sqrt [ 81 + 144] = sqrt [ 225] = 15 ft
So...the rope length is 13 + 15 = 28 ft
