Consider the picture below. B c f E d b triangle ABC D' Click on the graph to open it in a new window. e F triangle DEF The pictured triangles ABC and DEF are similar triangles. Find the length of one side of= 1. If b = 4 m, e = 12 m, and f = 21 m, then c = . 2. If c = 8 ft, d = 20 ft, and f = 16 ft, then a = | ft. NOTE: Round your answer to four decimal places.
