Question

In a cyclic quadrilateralABCD if angle A =105 angleB=70 find angleCand angleD

Answer 1

Answer:

∠C=75°

∠D=110°

Step-by-step explanation:

we know that in a cyclic quadrilateral, sum of opposite angles is 180

∴A+C=180°

105°+C=180°

C=180°-105°

C=75°

and

B+D=180°

70°+D=180°

D=180°-70°

D=110°
