Question

Which is a possible value for x?
Answer
18
1
17
15

Answer 1

the 'Z' angles are equal
so 3x - 4 = 47
3x = 51
x = 17

Answer 2

it says that it was wrong

Answer 3

angles ABD and BDC are equal because the two lines AB and DC are parallel. ah sorry - i misread the diagram AB = DC NOT parallel - i'll take another look.

Answer 4

as the side 16 is opposite the angle 47 degrees and the 3x-4 is opposite side of length 13.and the sides containing the two angles are equal, then 3x-4 < 47
so 3x < 51 and x < 17

Answer 5

length 1 is impossible so the answer is 15.
