8 0

Answer:

Step-by-step explanation:

To get x by itself you would need to subtract 5 by 5 to cancel out 5 so now you just have x = 7 And since you subtracted 5 from that side you have to do the same to the other side which is 12 so 12-5 is 7

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
