  1. Question 1

    Q1. A tree is broken by the wind and the top strikes the ground at an angle of 30°. If the distance from the foot of the tree to the point where the top touches the ground is 20 m, find the height of the tree.

    • A) 20√3 m
    • B) 20 / √3 m
    • C) 20(1 + 1/√3) m
    • D) 20(1 + √3) / √3 m

    Answer: 20(1 + √3) / √3 m

    Explanation: Using trigonometric ratios, we can find the height of the broken part and add it to the height of the remaining part.
