Answer:

The smallest angle is COD

Explanation:

  • Angle AB = 180°

so

180 = 2a + 62 + 54 - a + 5a - 20

180 = 6a + 96

180 - 96 = 6a

84 = 6a

a = 14

  • find angle AOC

2a + 62 =

2 * 14 + 62 =

28 + 62 =

90°

  • find angle COD

54 - a =

54 - 14 =

40°

  • find angle DOB

5a - 20 =

5 * 14 - 20 =

70 - 20 =

60°
