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°
