a lighthouse that is 120 ft tall casts a 160 - ft long shadow on the surface of water. what is the distance from the top of the
lighthouse to the end of the shadow?
1 answer:
The length of the lighthouse (120) and the length of the shadow (160) form the sides of a triangle.
Use the formula a^2 + b^2 = c^2
120^2 + 160^2 = c^2
