Question

If segment AB is 4 units, segment AD is 23 units, and segment CD is 12 units, what is the length of segment BC?

PLEASE HELP

AD=23 because it is the same length as the top line. 12+4 is 16 and 23-16=7. X=7

Answer 2

I think it’s 8 I’m not sure I did 12 divided by 2 which is half and got six and then I did 4 divided by 2 which is 2 and I added 2 and 6 and that’s how I got 8 hope this helped
