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°
