plz explain it step by step
I have my maths exam tomorrow​

Answer 1

Answer:

∠ECD = 130°

Step-by-step explanation:

Let's draw an imaginary line on line CE and the point of intersection of line AO and CD be F.

As, line FCE||ODB

∵∠FOD corresponds ∠AFC, therefore ∠AFC=50°

If added,2 opposite angles make 180°

∴180°=∠AFC + ∠ECD

⇒180°=50° + ∠ECD

⇒∠ECD= 180° - 50°

⇒∠ECD= 130°
