If the height of a tower and the distance of the point of observation from its foot, both, are increased by 10%, then the angle of elevation of its top

Answers (1)

If the angle elevation is A        

tan A = h/x

Where h is height and x is the distance from the tower,

If both are increased by 10 %, then the ratio will remain the same. Hence Angle of elevation also remains the same.
