Question

Joey, who is 6 feet tall. He stands 75 feet away from a building. He looks up at the building with an angle of elevation of 58

What is the height of the building to the nearest foot?
A
120 feet
B
126 feet
c
142 feet
D
148 teet

Answer 1

the answer is A

Explanation:

If you draw it then the height of the building (x) is the opposite, the adjacent is 75 (it's in between a 90 degree angle and the 58 degree angle). With this you have tan (58) = x/75

Then you add multiply 75 on the other side

75 tan (58) = x

After putting it in a DEG calculator, x = 120.03.
