Answer 1

Answer:

✍️ ∠ACE  = 80°

∠ACB  = 65°

∠ABC  = 35°

Step-by-step explanation:

∠BAC = ∠ACE   (alternative angles)

=> ∠ACE  = 80°

∠ACB + ∠ACE + ∠ECD = 180°  ( straight line)

=> ∠ACB + 80° + 35° = 180°

=> ∠ACB  = 65°

∠ACB + ∠BAC + ∠ABC  = 180°  ( sum of angle of triangle)

=> 65° + 80° + ∠ABC  = 180°

=> ∠ABC  = 35°

Answer 2

Answer:

Step-by-step explanation:

The solution is already on the image! Why did you ask us to help you? Believe in yourself!! :)

Only, I don't see the measure of angle AED

m∠AED = 180° - 35° = 145°
