PLEASE NOTE: QUESTION 1
Angle ADE = 32 degrees
Explanation
Angle BCE is 53, angle ACE is going to be 32. Shape ACOD is a guard, hence angels inside should add up to 360. So 360 - 276 - 42. Answer we divide by 2 we get 21 degrees which is angle BCA. Then to get ACE you then say 53 - 21 to get 32 degrees. So ADE = 32 degrees, angles subtended by the same chord
