Question

ABCD is cyclic .If angle B=70°,then find the measure of angle D=?​

Answer 1

Answer:

Since it's a cyclic quadrilateral, and b = 70 degrees, d will be 180 - 70 = 110 degrees.

Step-by-step explanation:

Hope it helps.

Answer 2

Answer:

D = 110°

Step-by-step explanation:

ABCD is cyclic quadrilateral .....(Given)

angle B + angle D = 180° .....(The opposite angles in a cyclic quadrilateral are supplementary. )

70°+ angle D =180°

angle D = 180°-70°

angle D = 110°

The measure of angle D is 110°
