The required height of the building is 53.31 feet.
A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.
Given that,
Angle of elevation from the first car A to the top of the apartment building = 48 degrees,
Angle of elevation from the second car B to the top of the apartment building = 64 degrees.
Also, car B is 22 feet above the car A.
Let the height of the building is h feet.
And distance from the car B to the building is x feet.
Use formula of tan θ,
tan 64 = h / x
2.050 = h/x
x = h / 2.050 (1)
And tan 48 = h / x + 22
1.1106 = h / x+ 22 (2)
By solving equation (1) and (2)
1.1106 = h / (h/2.050 + 22)
1.1106 = 2.050h / h + 45.1
1.1106h + 50.08 = 2.050h
0.9394 h = 50.08
h = 53.31
The height of the building is 53.31 feet.
