The answer to your question is 28.37 m
Step-by-step explanation:
Data
height of the transit = 2 m
distance to the tower = 35 m
angle = 37°
Process
To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.
tan Ф = Opposite side / Adjacent side
-Solve for Opposite side
Opposite side = Adjacent side x tan Ф
1) Substitute values
Opposite side = 35 x tan 37°
2) Simplification
Opposite side = 35 x 0.7536
Opposite side = 26.37 m
3) Calculate the height of the tower.
Height = 26.37 + 2
= 28.37 m
