  1. Question 1

    Q1. A ladder 10 m long leans against a wall, making an angle of 45° with the ground. How far is the ladder's foot from the wall?

    • A) 5√2 m
    • B) 10 / √2 m
    • C) 5 m
    • D) 10√2 m

    Answer: 5√2 m

    Explanation: Using cos(45°) = adjacent / 10, we get adjacent = 10 * cos(45°) = 10 * 1/√2 = 5√2 m.
