Answer:
h = + 6 ft
Explanation:
Here we're dealing with a right triangle and may therefore apply the P, Pythagorean Theorem.
The hypotenuse is 10 ft and the horizontal leg is 8 ft. Thus, if h is the height of the highest point of the slide,
(8 ft)^2 + h^2 = (10 ft)^2, or
64 ft^2 + h^2 = 100 ft^2, leading to h^2 = 36 ft^2.
Then h = + 6 ft
