Question 1142935
<br>
The largest angle is twice the smallest angle.
So let x be the measure of the smallest angle; then 2x is the measure of the largest.<br>
The sum of the smallest and the largest is twice the other angle.
The sum of the largest and smallest is x+2x = 3x; that is twice the measure of the third angle.  So the measure of the third angle is 1.5x.<br>
The sum of the measures of a triangle is 180°.
{{{x+2x+1.5x = 180}}}<br>
