Question

The measures of all of the interior angles of a triangle are in the extended ratio 1 : 2 : 3. The value of the smallest angle is:

Answer 1

30 degrees

Step-by-step explanation:

Let the ratio's be in x, 2x, 3x

Total Interior Angle of a triangle sum ups to 180°

• x + 2x + 3x = 180°

• 6x = 180°

• x = 180°/6 = 30°

The smallest angle which is x is 30°
