Hello! To find the answer to this, let’s do 6x + 4x = 180. Combine like terms and you get that 10x = 180. Divide each side by 10 in order to get 18. Angle 1 = 108 degrees and Angle 12 = 72 degrees. Odd number angles match each other and even number angles match each other. In this case, 5 has the same angle measurement as 1, which is 108. The answer is D: 108 degrees.

The discriminant of a quadratic is the expression inside the radical of the quadratic formula.
![{b}^{2} −4(ac)](https://tex.z-dn.net/?f=%20%7Bb%7D%5E%7B2%7D%20%E2%88%924%28ac%29)
Substitute in the values of a, b, and c.
![{10}^{2} −4(6 \times (−1))](https://tex.z-dn.net/?f=%20%7B10%7D%5E%7B2%7D%20%E2%88%924%286%20%5Ctimes%20%28%E2%88%921%29%29)
