The horizontal distance between the lighthouse and the shore is 896 feet.

Trigonometric ratio

Trigonometric ratio is used to show the relationship between the sides and the angles of a right angled triangle.

The angle of elevation is 7°. Let d represent the horizontal distance from the lighthouse and the shore. Hence:

tan(7) = 110/d

d = 110 / tan(7)

d = 896 feet

The horizontal distance between the lighthouse and the shore is 896 feet.
