  1. Question 1

    Q1. A right triangle has one angle of 30° and the side adjacent to it is 20 m. What is the length of the hypotenuse?

    • A) 20 / √3 m
    • B) 20 * √3 / 2 m
    • C) 20 * 2 / √3 m
    • D) 40 / √3 m

    Answer: 40 / √3 m

    Explanation: Using cos(30°) = 20 / hypotenuse, we get hypotenuse = 20 / cos(30°) = 20 / (√3 / 2) = 40 / √3 m.
