Question
A tree breaks due to a storm and the top touches the
ground 30 meters away from its base, making a 30-degree angle with the ground. What was the height of the tree before it broke?Solution
Using trigonometry (tan) = opposite/adjacent): tan 30° = Height/30 Since tan 30° = 1/√3 1 /√3 =Height/30 Height = 30×1/√3  ≈ 17.32 meters Approximating to the closest option: 15 meters
