Find the angle measure x in the figure

  x = 25

Step-by-step explanation:

Make use of the fact that the sum of angle measures in a triangle is 180°.

  (2x+15)° +(3x+5)° +(x+10)° = 180°

  6x +30 = 180 . . . collect terms, divide by °

  x +5 = 30 . . . . . . divide by 6

  x = 25 . . . . . . . . . subtract 5

Check

This value of x makes the angle measures be ...

  A = (x+10)° = 35°

  B = (3x+5)° = 80°

  C = (2x+15)° = 65°

These angles total 180°.
