the answer is 60root3 you can do it by using trignometry.

dolaamar · Answer

To find the distance from the observer to the lighthouse, we used the tangent function in trigonometry. The equation d = 60 3 ​ was derived, and calculated to be approximately 104 feet. This represents the distance to the nearest foot between the observer and the base of the lighthouse.
