Question

ABCD is a cyclic quadrilateral if angle BCD is equal to 120 and Angle ABD is equal to 50 degree find angle ADB

Answer 1

Answer: 70;

Step-by-step explanation:

Since, ABCD is a cyclic quadrilateral

So, <BCD+<BAD=180°

120°+<BAD=180°

<BAD=180°-120°

<BAD=60°

In triangle ABD

<ABD+<BAD+<ADB=180°

50°+60°+<ADB=180°

<ADB=180°-110°

<ADB=70°
