The answers would be A, D, E, and F because they all have the same y-intercept, the y-intercept is the second number in the equation
BCDE=100+ 80+100+80 = 360 degree
BAC = 20 degree
DBC = 100 degree
BDE = 80 degree
2/7x-1/7x=100
subtract the 2/7x and the 1/7x
so it would be
1/7x=100
multiply 1/7 on both sides
so
x=100 times 1/7
solve
x=100/7
x=14 2/7
The answer is
0=2
2=3
4=4
6=5
