B. angle C=110
C.angle B=110
D.angle A=110
For the quadrilateral ABCD if Angle D=70 then the angle A cannot be equal to 110 if AB II CD .
It is a trapezoid in which the base angles are equal and the left and right side lengths are equal.
In an isoceles trapezoid the angles made by the base are equal. So if AB II CD and the angle D is 70then the angle C will be 70, Angle B will be 180-70=110 and angle A will be 180-110=70.
Hence the correct option for the given question will be option D.
