A yacht is anchored 90 feet offshore from the base of a lighthouse. The angle of elevation from the boat to the top of the lighthouse is 26 degrees. The distance between the yacht and the top of the lighthouse is about 100 feet. Which equation will allow you to find the height of the light house.

• Tan (26) = x/90

• Tan (26) = 90/x

• Sin (26) = x/90

• Sin (26) = 90/x
