answer of question 1 is:
let :be x
2x+3x=50°
5x=50°
x=10°
so,
2x=2*10°= 20°
3x=3*10°=30°
first angle is 20°,
second angle is 30°
let :be x
2x+3x=50°
5x=50°
x=10°
so,
2x=2*10°= 20°
3x=3*10°=30°

Angle1= 50°
Let Angle2=2x
Let angle3=3x
Angle1+angle2+angle3=180°....angle sum prop.
50°×2x×3x=180°
50+5x=180°
5x=130°
x=130/5 =26°
Angle 2= 2×26=52°
Angle 3=3×26=78°
Let Angle2=2x
Let angle3=3x
Angle1+angle2+angle3=180°....angle sum prop.
50°×2x×3x=180°
50+5x=180°
5x=130°
x=130/5 =26°
Angle 2= 2×26=52°
Angle 3=3×26=78°
tnx
