Answer:

  121°

Step-by-step explanation:

The sum of the angles of a triangle is 180°.

  (x)° +(x -5)° +(3x +25)° = 180°

  5x +20 = 180 . . . . . . . . . . . . . . collect terms, divide by °

  5x = 160 . . . . . . . . . . . . subtract 20

  x = 32 . . . . . . . . . divide by 5

Angle G is ...

  ∠G = (3x +25)° = (3·32 +25)°

  ∠G = 121°
