Answer:

See below ↓

Step-by-step explanation:

  • ∠G = ∠E and ∠F = ∠D [opposite angles in a ║gm]
  • 3x + 11 = 5x - 9
  • 2x = 20
  • x = 10

  • ∠G = 5(10) - 9 = 41°
  • ∠E = 3(10) + 11 = 41°

Measures of the angles are equal 360° (total degree measure) - [∠G + ∠E]

  • 360 - 82
  • 278
  • ∠F and ∠D = 1/2(278) = 139°
