The value of h in the given diagram is 72 ft. The correct option is the third option 72
Calculating the height of a triangle
From the question, we are to calculate h. h is the height of the triangle
First, we will the determine half the length of the base of the triangle.
Half the length of the base of the triangle = 42 ft/2
Half the length of the base of the triangle = 21 ft
Thus,
By the Pythagorean theorem, we can write that
75² = 21² + h²
5625 = 441 + h²
h² = 5625 - 441
h² = 5184
h = √5184
h = 72 ft
Hence, the value of h in the given diagram is 72 ft. The correct option is the third option 72
