You'll need 7.6 gallons of gas... all you do is divide 190 by 25 and get 7.6 as your answer
Pr(1/2) for both I believe. If not right sorry.
#18 Supplementary means two angles add up to 180 degrees. Angles JHF
#19. Complementary means two angles that add up to 90 degrees. Angles GHF
#20. Adjacent means two angles that have a common side and vortex that's why it does not work.
Hope this helps :)
