Answer 1

<S is 120 degrees

Explanation:

All angles in a triangle add up to 180

12x+4x+2x=180

18x=180

x=10

So, 12(10)=120

Answer 2

120°

Explanation:

You want the measure of ∠S = 12x° in a triangle with the other two angles being 4x° and 2x°.

Angle sum theorem

The sum of angles in a triangle is 180°. That means ...

12x° +4x° +2x° = 180°

18x° = 180° . . . . . . . . . . collect terms

x° = 10° . . . . . . . . . . . divide by 18

12x° = 12(10°) = 120° . . . . . find the measure of 12x°, angle S

m∠S = 120°
