Answer 1

$1+2+3=6$

$Angle \: of \: ratio \: 1$

$= \frac{1}{6} \times 180$

$= 30$

$Angle \: of \: ratio \: 2$

$= \frac{2}{6} \times 180$

$= 60$

$Angle \: of \: ratio \: 3$

$= \frac{3}{6} \times 180$

$= 90$

Answer 2

Step-by-step explanation:

Let the angle be x

1x + 2x + 3x = 180°

6x = 180 °

x= 180/6

x= 30°

Ist angle = 30°

2nd angle = 2 × 30= 60°

3rd angle = 3× 30= 90°

4th angle = 4× 30= 120°
