Fill in the reason that justifies each step. Angle CDE and Angle EDF are supplementary. angles that form a linear pair are supplementary

m Angle CDE + m Angle EDF = 180 a. ?
x + (4x - 20) = 180 b. ?
5x - 20 = 180 c. ?
5x = 200 d. ?
x = 40 e.?

may i see the picture? it would a lot, xox

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

d is ur answer hopes this i dont really know how to explain it to u.
