Answer:
110, 70, 110, 70 degrees
Step-by-step explanation:
Since it's a cyclic quadrilateral, and b = 70 degrees, d will be 180 - 70 = 110 degrees.
Since ab II cd, it can either form an isosceles trapezium or a parallelogram.
In these, opposite pairs of angles are equal.
Therefore, the remaining angles are:
110, 70, 110, 70 degrees.
