please help i can afford to fail if you would like to help more theres alot more problems on my account

Step-by-step explanation:

We know that Angle 8 is equal to Angle 5. This is called a vertical pair. Since that we know both angles are equal, we can guess the rest of the Angles. Make an equation. x+80=180 (supplementary) X will equal 100 degrees. The Angles that are 100 degrees are 2,3,6, and 7. So now we know them. Angle 2 is equal to 100 degrees :)

Hope this helped.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
