∆abc =~ ∆def
what angle is congruent to < b?

a. < f

b. < a

c. < e

d. < d

∠E

Step-by-step explanation:

In ABC, we see that vertex B correspond to the end of the short leg of the triangle.

we simply go to DEF and try to find the same corresponding vertex that is at the end of the short leg of triangle DEF.

in this case, we can clearly observe that it is vertex E# and hence angle E is the answer.

1.4

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
