Answer:

  (a) (6x -3) +(2x -6) +x = 180

  (b) m∠L = 123°

     m∠M = 36°

     m∠N = 21°

Step-by-step explanation:

a) The sum of angle measures (in degrees) is 180°. The equation reflects this fact:

  (6x -3) +(2x -6) +x = 180

__

b) The equation simplifies to ...

  9x -9 = 180

  x -1 = 20 . . . . . divide by 9

  x = 21 . . . . . . . .add 1

Then the degree measures are ...

  m∠L = (6x -3)° = (6·21 -3)° = 123°

  m∠M = (2x -6)° = (2·21 -6)° = 36°

  m∠N = x° = 21°
