Based on Triangle Angle Sum Theorem, the sum of the angles inside a triangle must equal 180°.
Use the equation 2x + 4x + 6x = 180° to solve the measures of the angles in this triangle.

30°, 60°, and 90°
15°, 75°, and 90°
30°, 60°, and 90°
Explanation:
2x + 4x + 6x = 180
12x = 180
x = 15
So, the angles are:
2(15) = 30°
4(15) = 60°
6(15) = 90°
Which means the angles inside the triangle are 30°, 60°, and 90°.
