Answer:
Step-by-step explanation:
From the picture we can see that:
- ∠COE and ∠DOF are vertical angles as formed by intersection of lines CD and EF, so these angles are equal
- MO⊥AB as ∠MOB = 90°, therefore ∠AOM = 90°
Considering the above we get below to find x:
- 12° + 2x + 3x = 90°
- 5x = 90° - 12°
- 5x = 78°
- x = 78°/5
- x = 15.6°
And using this to find y:
- 48° + 3y = 90°
- 3y = 90 - 48
- 3y = 42°
- y = 42°/3
- y = 14°
