non-linear
Step-by-step explanation:
Let's solve for the answer to determine if it is rational.
it is a rational number.
180 is the degrees a straight line segment is. This means that
4x + 3x + 2x = 180.
Since these all have the same variable (x), then you can add the coefficients. (4,3,2)
9x = 180
180/9 = x
X = 20
