I don’t know the answer please help

Answer 1

Answer:

B

Step-by-step explanation:

You use tangent, and you set up an equation ,with h = height. You get "tan(64) = h/75" You multiply both sides by 75 and get "75tan(64) = h" You put that into a calculator, and get h is approx. 154, so B

Answer 2

Answer:

From the picture, the height of the building is the leg opposite to angle 64º. Also, 75 ft is the side equal to the adjacent side of the right triangle.

Considering:

$tan\theta=\frac{opp}{adj}$

$tan64\textdegree =\frac{height}{75}$

$2.050=\frac{height}{75}\\height=153.75ft$

Answer: 154 ft
