Scott set up a volleyball net in his backyard. one of the poles, which forms a right angle with the ground, is 6 feet high. To secure the pole, he attached a rope from the top of the pole to a stake 8 feet from the bottom of the pole. To the nearest tenth of a foot, find the length of the rope.

1. learn to recognize common Pythagorean triples in right triangles. The simplest is 3-4-5. This is just double that, or 6-8-10.

The rope is 10 feet long.

Or, you can do the algebra, using

r^2 = 6^2+8^2
and solve for r.
