A ladder leaning against a wall is making an angle of 60° with the ground. If the length of the ladder is 18 m, find the distance of the foot of the ladder from the wall.
Select an option to attempt
Correct Answer: Option B
Explanation
Ladder-wall trigonometry problem:Given: Ladder length = 18 m, angle with ground = 60°.The distance from the foot of the ladder to the wall is the adjacent side of the right triangle:The height reached on the wall (opposite side):Note: Option 1 (m) is the HEIGHT on the wall, not the distance from the wall. The correct answer for the distance from the wall is 9 m (Option 2).Distractor Option 4 () is incorrect.
