Answer:
x = 4.5
m∠VGT = 108°
Step-by-step explanation:
base on the given diagram
1. solve for - (refer to attached image 1)
- 3x + 6 = 5x - 3
- 6 + 3 = 5x - 3x
- 9 = 2x
- x = 9/2
- x = 4.5
2. solve for m∠VGT (refer to attached image 2)
- internal angle of VGT = 180
- ∠V/2 + ∠T/2 + ∠G = 180
- 66/2 + 78/2 + ∠G = 180
- 33 + 39 + ∠G = 180
- ∠G = 180 - 33 - 39
- ∠G = 108
