Answer:
B. x = 7/2 or x=-1/3
Step-by-step explanation:
You know both angles 6x² and 19x+7 have to be the same, so you can solve
6x² = 19x+7
6x² - 19x - 7 = 0
apply the quadratic formula and find
x = -1/3 or x = 7/2
now think carefully if the negative x is a realistic solution. It would lead to the angles being (2/3)°. This is not what the picture suggests, but it is also not wrong, so answer B seems the best.
