Find the missing angle measures:

Step-by-step explanation:

The given system of equations is

First, we need to rewrite the system in order

Now, we multiply the first equation by -3, and solve

This means the system of equation has infinite number of solutions, that is, it's a consistent system.

The reason of this result is because both equation represent the same line, it's like one line is on top of the other, sharing all points, that's why it has infinte solutions.
