There are three angles measured in degrees of a triangle where x is the largest angle, y is the middle angle, and z is the smallest
angle
• The measure of the largest angle is 40 degrees less than twice the sum of the measure of the other two angles.
• The measure of the largest angle is twice the smallest angle plus 10 degrees.
• The sum of the angles of a triangle can be written as x + y + z = 180.
