Question

what are the angles of DAB ?
need with steps​

Answer 1

Answer:

<A=70

Step-by-step explanation:

sum of opposite sides of a cyclic quadrilateral =180

so, 110+<A=180

<A=70

Answer 2

Answer:

70

Step-by-step explanation:

ABCD is a Cyclic Quadrilateral(A quadrilateral whose all vertices lie on a circle)

We know that the sum of the opposite angles of a cyclic quadrilateral is 180

So, angle A + angle C = 180

angle A + 110 = 180

angle A = 180 -110 = 70
