Question 502951: the measurement of the largest angle in a triangle is twice the measurement of the smallest angle. the third angle 10 degrees less than the largest angle. find the measure of each angle.

smallest angle =x
largest angle =2x
third angle = 2x-10
The sum of the angles of triangle = 180 deg
x+2x+2x-10=180
5x-10=180
5x=180+10
5x=190
x=38 deg
plug x
2x=>2*38=76 deg
2x-10=> 76-10 = 66 deg
***
66+76+38=180 deg
