Answer:
B. 3.99x10^-6
Step-by-step explanation:
I am attaching the full question...
Because AB is parallel to CD, the transversal line EF creates the same angles in AB and CD.
This means that 3x+40 = 4x
..........==>> x = 40 degrees
The answer you are looking for is 2& 3/10
4(x+7)=8x-20
4x+28=8x-20
28=4x-20
48=4x
x=12
Answer:
x=2m−6
