She stakes the rope, which is 8ft long, to the ground at a distance of 6 feet from the middle of her tent. About how tall is her tent?

Answer 1

If you are talking about this problem:

Then you would use the Pythagorean Theorem to solve for "h".

6² + h² = 8²

36 + h² = 64

h² = 64 - 36

h² = 28

h = √28

h ≈ 5.29 feet
