I cant figure out how to find x

Question

The farthest I got was 5x=218 and I'm not sure if that is even correct.

(Can't insert the picture so I will try to describe it)

It is a circle, there are 3 angles and you have to find 5.

2x + 3x + 142 =360

(1st angle) (2nd angle) (3rd angle)

Answer 1

5x = 360 - 142 = 218

x = 218/5 = 43.6

3x = 3(43.6) = 130.8 = 2nd angle

2x = 2(43.6) = 87.2 degrees = 1st angle

142 degrees = 3rd angle

87.2 + 130.8 + 142 = 360
