Answer:

95 degrees

Explanation:

In a quadrilateral where there are two pairs of parrallel sides, the angles adjacent to each other are supplementary and add to 180 degrees. This means Angle A + Angle B = 180, Angle B + Angle C = 180, Angle C + Angle D = 180 and Angle D + Angle A = 180. If Angle A is 85 degrees then Angle B is 95 degrees. There are only two distinct angle measures within the quadrilateral. All angles for the quadrilateral are 85 or 95 degrees.
