let the two angles be 3x and 7x
3x + 7x = 180 (linear pair)
10x =180
x=180/10
x=18°
angles are 54° & 126°
3x + 7x = 180 (linear pair)
10x =180
x=180/10
x=18°
angles are 54° & 126°

Heya,
Linear pair means = 180°
Ratio of angles forming linear pair = 3:7
Let first angle be 3x
And second angle be 7x
According to the question,
3x + 7x = 180°
10x = 180°
x = 180°/10
x = 18°
Therefore first angle will be; 3x = 3*18 = 54°
And second angle will be; 7x =7*18 = 126°
Hope this helps you...:)
Have a good day ....
