Answer:

121°

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°
