Easy
The angle of elevation of the top of a tower from a point on the ground 10 m away from its base is 60°. Find the height of the tower. (Use √3 = 1.73 where needed)
Explanation
Explanation
Let the height be h. In the right triangle formed, tan(60°) = height/distance = h/10. Since tan 60° = √3, we get h = 10 × tan 60° ≈ 17.3 m.
PRO TIP
Re-check your working by substituting the answer back into the original question.
