Im thinking line x, because the coordinates on lines y & e and f & z are the same, but flipped (first touching point for f is (3, 1) and first touching point for e is (1, 3). It gives the rules for lines y & e and f & z, but not for x? And line x is the only one that doesn't have another line like this.
The answer to this is A and D. A and D are both rational because they contain repeating numbers.
B) could've been the answer but it doesn't show any repeating numbers
C) Doesn't have a repeating number.
So A and D are the answers. (if there is only one option for this answer then D should be the answer)
Hoped this helped :)
Have a great day
Answer:
x = 12
Step-by-step explanation:
The two marked angles where the transversal crosses the parallel lines are alternate interior angles, so are congruent. This fact gives you the relation you need to solve for x.
4x +12 = 60
4x = 48 . . . . . . subtract 12
x = 12 . . . . . divide by 4
