☞ We know ,
sum of all the angles of a triangle is 180°
Let the first angle be :- 3x
Let the second angle be :- 2x
Let the third angle be :- 7x
Therefore sum of the angles = 3x + 2x + 7x = 12 x
Therefore, first angle = ( 3x / 12x ) × 180 = 45°
Second angle = ( 2x / 12x ) × 180 = 30°
Third angle = ( 7x / 12 x ) × 180 = 105°
Ans) The angles are 45° , 30° , 105°
