Question

Find each angle measure in the triangle.
3x°
2xº
4xº

Answer 1

Explanation:

3x+2x+4x=180

9x=180

x=180/9=20

3x=3×20=60°

2x=2×20=40°

4x=4×20=80°

Answer 2

The total measure of angles in a triangle is 180°.

3x° + 2x° + 4x° = 180°

9x° = 180°

x° = 180° ÷ 9

x° = 20

Our 3 angles are:

3(20) = 60°

2(20) = 40°

4(20) = 80°

Done.
