Rectangle ADEF and isosceles trapezoid FBCE both have a base of 4. The lower base angles of the trapezoid are 45° and the legs of the trapezoid are 2. How long is BC? Round your answer to the nearest tenth.

2. Draw FBCE with BC at the top, at FE as the base. Draw lines straight down from B and C to FE, to form triangles with angles, 45, 45, 90. This is a 1:1:sqrt(2) triangle the length of each of the sections is 6 / sqrt(2) = 3 * sqrt (2) There are 2 of the triangles. 12 - 2 * (3 * sqrt (2)) = 12 - 6 sqrt(2) = 12 - 8.485 = 3.5
