Question

When a plane mirror is placed horizontally on a level ground at a distance of 60 meters from the foot of a tower, the angle between the incident ray from the top of the tower and horizontal is ${45}^{\circ }$. Then height of the tower is

• A. 40 m
• B. 60 m
• C. 48 m
• D. 22 m

Answer 1

The correct option is B 60 m

From the figure,
tan ${45}^{\circ }=\frac{h}{60}$
h = 60 m
The height of the tower is 60 m.
