Answer:
Step-by-step explanation:
Because the four angles share a common point and because they start with the top of 2x and end there, the total number of degrees travelled is 360 -- the same as though the origin were at the meeting place of the 4 given angles and the center of a circle.
3x + 3x + 4x + 2x = 360 degrees. Combine
12x = 360 Divide by 12
12x/12 = 360/12
x = 30
