Use the diagram below to answer the question that follows.
I couldn't copy the diagram into this. It basically shows a Triangle ACD with CD=100ft. Then another line intersects above angle A and reads BE= 30ft.
AB=50ft. and BC=? That is the part it wants you to solve.
The diagram represents a method for estimating BC, the width of a river. Given that AB = 50 feet, CD = 100 feet, and BE = 30 feet, which of the following is the best estimate for BC?
How do you solve this?
