A triangle has three interior angle measures; x is the largest angle, y is the next largest angle, and z is the smallest angle.

The measure of the largest angle is 40 degrees less than the sum of the measure of the other two angles.
The largest angle is twice the smaller angle minus 30 degrees.
The sum of the triangle's interior angles is x + y + z = 180.

Which two equations represent the remaining angle relationships?

Select each correct answer.


x = y + z + 40
x, = , y, + , z, + 40

x=2z−30
x equals 2 z minus 30

x=30−2z
x equals 30 minus 2 z

x=y+z−40
x equals y plus z minus 40

x=y−z+40
