In a triangle, the measure of the second angle is twice the measure of the first angle. the third angle is equal to the sum of the other angles. which of the following could represent the measures of the three angles?

Hi

As stated:

x , the first
2x, the second

3x, the third (sum of first two)

x + 2x + 3x = 180°
6x = 180°
x = 30°

Measures of the Angles would be 30°, 60°, 90°
