Do I need to explain?
These aren't that hard--especially once you've done the first 13 questions. There are many 45-45-90 triangles in there.
14. ∠BCO = 45°
15. ∠GOF = 45°
16. ∠OFG = 45°
17. ∠GFH = 180° - ∠JFH = 58°
18. ∠FGH = 90°
19. ∠EFJ = 45°
20. ∠GOC = 180° (the points are collinear)
Answer i do not know i think u need to divide something
Maybe tell the choices you have

Hello from MrBillDoesMath!
Answer: b
Discussion:
7b + 3 - 4b = 3 - 3(b+4) =>
7b + 3 - 4b = 3 - 3b -12 =>
(7b - 4b) + 3 = -3b - 9 =>
3b + 3 = -3b -9 => Add 9 to both sides
3b + 12 = -3b -9 + 9 =>
3b + 12 = -3b => ( add 3b to both sides)
6b + 12 = 0 => (subtract 12 from both sides)
6b = -12 =>
b = -12/6 = -2
Thank you,
