Question

please give me answer​

Answer 1

Explanation:

Angle CDE is equal to angle ABC

its a property but for learning i will derive this for you mark my answer as BRAINLIEST

angleABC+angleADC= 180(opp angles of a cyclic quad)

therefore angleADC=80⁰

then angle ADC+angleCDE = 180⁰(LINEAR PAIR)

SO WE GOT ANGLE CDE = 100⁰

MARK THIS AS BRAINLIEST
