Answer:
Step-by-step explanation:
The length of the ladder represents the hypotenuse of the right angle triangle.
The distance of the top of the ladder from the ground represents the opposite side of the right angle triangle.
To determine the ground distance from the base of the building to the foot of the ladder, x which represents the adjacent side of the right angle triangle,
we would apply trigonometric ratio,
Cos θ = adjacent side/hypotenuse
Cos 75 = x/28
x = 28 × 0.2588
x = 7.2464 feet
