Question

square abcd is cyclic if lb=110° find measure of ld​

Answer 1

Answer:

Opposite angles in a cyclic quadrilateral are supplementary,

(The angles add up to 180.)

So, if angle B is 110, then angle D would be 70.

(However I don't think that the quadrilateral you have mentioned could be a square, since all angles of a square are in fact right angles, 90 degrees)

Hope I was able to help :)
