Question

At a horizontal distance of 200 m from the base of an observation tower, the angle between the

ground and the line of sight to the top of the tower is 8°. Sketch and label a diagram to represent
the information in the problem. How high is the tower to the nearest metre?

Hope this helps. Any more questions?

Answer 2

Answer:

28 m

Explanation:

The relevant trig relation is ...

Tan = Opposite/Adjacent

tan(8°) = height/distance to base

height = (distance to base)tan(8°) = (200 m)tan(8°)

height ≈ 28 m
