The total measure of a circle's arc lengths is 360 degrees. We can add up all of the arc lengths of the circle, set it equal to 360, and solve for x. The proportion of arc lengths will be used in that that is how many x's each arc gets.

3x + 5x + 4x = 360

12x = 360

x = 30

Arc AB: 90 degrees

30 x 3 = 90

Arc BC: 150 degrees

30 x 5 = 150

Arc AC: 120 degrees

30 x 4 = 120

Hope this helps!! :)
