Given : One angle of a triangle measures 30 degree and other two angles are in the ratio 3 : 2 .
To find : angles .
Solution:
Let say other two angles are
3x and 2x
Sum of all angles of a triangle = 180°
=> 3x + 2x + 30° = 180°
=> 5x = 150°
=> x = 30°
3x = 3 * 30° = 90°
2x = 2 * 30° = 60°
Angles are 90° and 60°
