 m∠L = 5x - 28
m∠N = 3x - 10

      m∠L ≡ m∠N
  5x - 28 = 3x - 10
- 3x         - 3x
  2x - 28 = -10
      + 28  + 28
         2x = 18
          2      2
           x = 9

m∠L = 5x - 28
m∠L = 5(9) - 28
m∠L = 45 - 28
m∠L = 17

m∠N = 3x - 10
m∠N = 3(9) - 10
m∠N = 27 - 10
m∠N = 17

  x + 17 = 180
     - 17    - 17
          x = 163

m∠O = 163
