Answer:
The answer to your question is the letter A) 53.1 feet
Step-by-step explanation:
Data
Adjacent side = 20 ft
angle = Ф = 67°
distance from the eyes to the ground = 6 ft
Opposite side = ?
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
- Substitution
Opposite side = 20 x tan 67
-Simplification
Opposite side = 20 x 2.36
- Result
Opposite side = 47.1 ft
Height = 47.1 + 6
= 53.1 ft
