  1. Question 1

    Q1. A ladder 10 m long leans against a wall, making an angle of 60° with the ground. How high up the wall does the ladder reach?

    • A) 5√3 m
    • B) 8.66 m
    • C) 10 m
    • D) 5 m

    Answer: 8.66 m

    Explanation: Using trigonometric ratios, sin(60°) = height / 10. So, height = 10 * √3 / 2 = 8.66 m.
