Answer 2

Answer:

Step-by-step explanation:

1) Angle C = 180- 100

=80 (opposite angles of cyclic Quadrilateral)

Angle B= 180-80=100 (DC II AB) (angle c and angle b are co interior angles)

2) angle CDB= 35 (Angle opp. To equal sides are equal)

Angle DBC + Ange CDB + Angle BCD = 180

35+35+Angle BCD=180

Angle BCD = 110

Angle A = 180 - Angle BCD (opp. Angles of cyclic Quadrilateral)

Angle A= 70
