Answer:
D
Explanation:
the right triangle contains h , the horizontal leg and the sloping side which is the hypotenuse of the right triangle.
the horizontal leg is half the measure of the side of the square base.
horizontal leg = 8 ÷ 2 = 4
using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
h² + 4² = 10² ( subtract 4² from both sides )
h² = 10² - 4² ( take square root of both sides )
h =
