A ladder leaning against a wall makes an angle with the horizontal ground such that = 125. If the height of the top of the ladder from the wall is 24 m, then what is the distance (in m) of the food the ladder from the wall?

Answer: Option C

Solution

Answer: Option C

Solution:

$$\begin{array}{rl}& \tan \theta =\frac{12}{5}\\ & 12\text{ unit}\to 24\\ & 1\text{ unit}\to 2\\ & BC=5\text{ unit}=5\times 2=10\text{ m}\end{array}$$
