Answer:
x=25.6°, left angle is 80.7°, right is 99.3°.
Step-by-step explanation:
The two expressions add to 180°.
Left angle is 3x+4°. Right side angle is 4x-3°.
Equation is 7x+1°=180°, 7x=179°, x=(179/7)° = 25.6°
Well since a circle has 360 degree, and theh give you one with 120 degree, you can find the other one by subtracting 120 from 360 to get 240 degree.
