Use the diagram to answer the question. Fill in the blank for the letter given with the missing reason in the flow proof. Please help me out :(

a)M5=40º

b)M2=140º

c)M2 and M5 are supplementary angles

d)M2 and M5 are same side interior angles

e) A||B

Step-by-step explanation:

Remember that same side interior angles are the angles that are located on the same side of a straight line that cuts through two parallel lines, and these angles are supplementary, meaning that the sum of both of them will always be 180º. So by stating that M5 and M2 add up to 180º and they are on the same side of a straight line cutting through two straight lines we can prove that those two lines are parallel.

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

b) the dogs need to shift their focus to human scent.
