Question 357380: A customer wants to make a teepee in his backyard for his children. He plans to use lengths of PVC plumbing pipe for the supports on the teepee, and he wants the teepee to be 6 feet across and 4 feet tall (see figure). How long should the PVC plumbing pipe be?
I tried to copy and paste the figure but I'm not sure if you can see it or not.

If you look at the tepee from the side you will see an isoceles triangle whose height is 4 feet and whose base is 6 feet.
If you drop a line from the apex perpendicular to the base you will have two right triangles. The height of the right triangle is 4 feet and the base will be just half of the width of the base of the isoceles triangle, or 3 feet.
You need to find the length of the hypotenuse of the right triangle.
Use:
Substitute a = 3 and b = 4

Take the square root of both sides.

The PVC plumbing pipe should be 5 feet long.
