Trapezoid math question!!!!!?

1) Parallelogram ACFD is split in two parts so that ABED and FEBC are congruent isosceles trapezoids. What are the measures of all the angles of trapezoid FEBC if angle D is 46°? 2)Two congruent "door-stop" trapezoids are placed edge-to-edge with measurements and markings as shown. How long is the upper base of... show more 1) Parallelogram ACFD is split in two parts so that ABED and FEBC are congruent isosceles trapezoids.
