Answer:
109.5°, 120°, 109.5°
Explanation:
The bond angles that are marked as a, b and c in the given molecules is in the order of :
Angle a : 109.5°
Nitrogen is 
hybridized and the geometry is tetrahedral. So the bond angle is 109.5°
Angle b : 120°
Carbon is 
hybridized, so the shape is trigonal planer and the bond angle is 120°
Angle c : 109.5°
Carbon is hybridized and the geometry is tetrahedral. The bond angle is 109.5°
