Question

in the given figure ABCD is a cyclic quadrilateral in which AB is parallel to DC if angle BAD = 100 then find angle ADC​

Answer 1

Answer:

angle ADC 80°

Step-by-step explanation:

∠BAD+∠BCD=180° (opposite angles of a cyclic quadrilateral are supplementary).

∴100°+∠BCD=180°

∠BCD=80°

(ii) ∠ADC=∠BCD (Alt angles are equal)

∠ADC=80°

(iii) ∠ABC=∠BAD (Alt angles are equal)

∠ABC=100°

because the opposite side of a cyclic quadrilateral are supplementary.
