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

miss Akunina [59]

Area = side AB * side BC = (5x + 5x + 3)(3x + 92x - 4)

= (10x + 3)(95x - 4) = 950x^2 - 40x + 285x - 12

= 950x^2 + 245x - 12 Answer

This cannot be negative so restriction on x is 950x^2 + 245x > 12
That is x > 0.0421
