Find the value of x I need the answer

Answer:
31
Step-by-step explanation:
You can solve this by remembering that angles on opposite quarters of intersecting lines will be equal to each other.
This means we can simply say:
3x + 7 = 100
3x = 93
x = 31
Step-by-step explanation:
3x + 7°= 100°
3x=100°-7°
3x=93
x=93/3
x=31
I guess its right.
