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?

A 30 meters Correct Answer Incorrect Answer
B 15 meters Correct Answer Incorrect Answer
C 20 meters Correct Answer Incorrect Answer
D 25 meters Correct Answer Incorrect Answer

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
