If we solve the given quadratic for y, we get y=-x and y=-x/2.
I assume what is being asked is to find the angle between these two lines?.
There is a formula for finding the angle between two lines.
It is:
Where m1 and m2 are their respective slopes of -1 and -1/2.

Is that what you were getting at?.
