A polygon with sides: 154-x, 50-2x, x+120, and x^2 + 7x.
Solve for x and give each angle, if necessary.
Actually it is not a polygon since it has a curve in it.
Doing a sketch, you should easily find the angle and intersect of the lines.
This is an example, it is NOT one of the vertexes.
For the parabola, I would use the derivative to find the slope at the intersect.
If needed ask for further explanations.
I interpreted this to mean that these were the lengths of the sides, not equations of the lines. But I suspect that masters is right and they are really supposed to be measures of the angles so that they add to 360.
