D. y = 6x...subbing in (2,12)...x = 2 and y = 12
12 = 6(2)
12 = 12 (correct)
so (2,12) is a solution to : y = 6x
I would chose B because the x will carry over to both
Answer:

Step-by-step explanation:
The measure of angle A is ...
180° -55° -45° = 80°
From largest to smallest, the angles are ∠A, ∠C, ∠B. Then their opposite sides will be in order from longest to shortest:
