Answer:
27; C; B; D
Step-by-step explanation:
1. B = 120 degrees, and C = 60 degrees. Q = 90 degrees, because B + C = 180 degrees, and the triangle BQC has angle B and angle C bisected. If B = 120 degrees, then the height is equal to 9 sqrt 3, which makes BC equal to 27.
2.C
3. B (You don't actually know if any of the sides are parallel.)
4. D
