Respuesta :
smaller angle= 60°
larger angle= 120°
equation
2x + x = 180°
3x = 180°
x = 60°
2x = 2 × 60 = 120°
60° + 120°= 180°
larger angle= 120°
equation
2x + x = 180°
3x = 180°
x = 60°
2x = 2 × 60 = 120°
60° + 120°= 180°
The smaller angle is 60° and the bigger angle is 120°
The sum of the angles must be equal to 180°.
Let the smaller angle be represented by x
Therefore, the bigger angle will be = (2 × x) = 2x
Therefore, the value of the angles will be:
2x + x = 180°
3x = 180°
Divide both side by 3
3x/3 = 180°/3
x = 60°
Then, 2x = 2 × 60° = 120°
Therefore, the smaller angle is 60° and the bigger angle is 120°.
