Question
Answer:
Angles EFG and ABC are supplementary to DBC, which means that EFG and ABC are the same angle.Supplementary means that two angles = 180. You can set the two equations of ABC and DBC up so that both equations will add to 180.
(18x + 28) + (7x + 27) = 180
Combine like terms.
18x + 7x = 25x
28 + 27 = 55
25x + 55 = 180.
Subtract 55 from both sides.
25x = 125
Divide both sides by 25 to get x by itself.
x = 5
Plug x into angle ABC.Β
18(5) + 28
90 + 28 = 118
The answer is A.
