Answer:
x = 25
Step-by-step explanation:
By the property,
Equal chords subtend equal angles at the center of the circle. Therefore, measures of arcs having equal central angles will be equal.
2x + 4x + (3x + 30) + (3x + 30) = 360°
(2x + 4x + 3x + 3x) + (30 + 30) = 360
12x + 60 = 360
12x = 300
x = 
x = 25
