Question

This is the last question I need help on, thanks for helping me on this.

Answer 1

the answer is 70 hope u have good day

Answer 2

BC= 70

Explanation:

If AC is equal to 140 and B is the midpoint of the line, then that would mean the line would be split in half thus having measures BA and BC. Both of the measures would have half of the full length so that would mean that BA and BC equals 70 since 140/2= 70
