Hi, I needed some help with these two trapezoid questions I couldn't understand.

1) ABCD is a trapezoid with bases AB and DC. We know that Angle C=60 Degrees and Angle D=45 Degrees. If AB=5-2sqrt3 and BC=4, what is $DC?

2) The ratio of the four sides of a trapezoid is 2:1:1:1. The area of the trapezoid is 27sqrt 3. Find the length of the median of the trapezoid.
