Answer:
C. x = 1
Step-by-step explanation:
To solve this problem the best way is to use the quadratic formula. First make everything equal to 0 by adding 3 to both sides.
3x^2 - 6x + 3 = 0
The quadratic formula is:
. Substitute the values of a, b, and c into the formula. Keep in mind:

Therefore, x = 1.
For one since since the angles should add up to 180 degrees we must start by adding 55 and 25 which is 80 so 180-80=100 which means c is 100 degrees and for the other I'm going with C
