The sum of measures of angles of a triangle is always 180°, so you have

... (2x)° + (3x)° + (x+30)° = 180°

... 6x + 30 = 180 . . . . . . . . . . . . . collect terms

... 6x = 150 . . . . . . . . . . . . . . . . . subtract 30

... x = 150/6 = 25 . . . . . . . . . . . . divide by 6


The appropriate choice is

... B 25
