Answer:

  • 80°

Step-by-step explanation:

See the picture

It should be self-explanatory

The top part of the angle a is:

  • 35° + 165° - 180° = 20°

The bottom part of the angle a is:

  • 180° - 120° = 60°

The measure of angle a is:

  • 20° + 60° = 80°

Something like in the picture

Now,

a = BNU

Also,

BNU + BNM = 165°
