  1. The angle sum of a trapezium must be 360° , so

    4x + 6x+10 + 3x-10 + 5x = 360
    18x = 360
    x = 20

    angle A = 80°
    angle B = 130°
    angle C = 50°
    angle D = 100°

    I don't see any perpendicular sides.
    Your question contains a contradiction.

  2. I think he meant AB parallel to DC, if vertices are labeled in cyclic order
