  1. Question 1

    Q1. In a right triangle, the hypotenuse is 15 m and one angle is 30°. What is the length of the side opposite the 30° angle?

    • A) 7.5 m
    • B) 15 / √3 m
    • C) 15√3 m
    • D) 7.5√3 m

    Answer: 7.5 m

    Explanation: Using sin(30°) = opposite / 15, we get opposite = 15 * sin(30°) = 15 * 1/2 = 7.5 m.
