A ladder is leaning against a wall, making an angle of 45° with the ground. If the length of the ladder is 10√2 m, find the height of the wall.
Q1. A ladder is leaning against a wall, making an angle of 45° with the ground. If the length of the ladder is 10√2 m, find the height of the wall.
Answer: 10 m
Explanation: Using trigonometric ratio: sin(45°) = height / 10√2, so height = 10 m.
