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 = $\frac{300}{12}$

x = 25
