Answer 1

answer choices are

B. 6
C. 3
D. 8

Answer 2

Ok first we have to understand that:
AB is congruent to DF
and
BC is congruent to FE
and
CA is congruent to ED

And since we are trying to to solve for EF (3x - 4) we have to set it to equal its congruent side: CB which equals 20

so:
3x - 4 = 20
+ 4 +4

3x = 24
/3 /3

x = 8
