A stick of length 48 cm is at an inclination of 60° to a wall with its bottom touching the floor of the wall. Find the length from the floor to the point where the stick touches the wall.
Show answer & explanation
Correct answer: A
Explanation
Given:
Stick length = 48 cm
Angle with the wall = 60°
Formula:
sinθ = opposite side / hypotenuse
sin60° = height / 48
√3/2 = height / 48
Height = 48 × √3/2 = 24√3 cm
