Question

From the top of a 60 m high building, the angles of depression to two points on the ground on the same side of the building are \( 30^\circ \) and \( 60^\circ \). What is the distance between the two points?

• A. \( 40\sqrt{3} \, \text{m} \)
• B. \( 20\sqrt{3} \, \text{m} \)
• C. \( 60 \, \text{m} \)
• D. \( 80 \, \text{m} \)

Hint:

Use trigonometric ratios to find distances in height and distance problems.
