HALP MEH PLZ

Answer 1

I meant one inch sorry

Answer 2

length of segment BC (x):
x + x - 1 + x + x - 1 - 10 = 72
4x = 84
x = 21

answer: 21 inches is the length of segment BC.

proof (perimeter is 72 inches):
= (21 - 1) + 21 + ([{21 - 1} + 21] - 10)
= 20 + 21 + ([20 + 21] - 10)
= 41 + (41 - 10)
= 41 + 31
= 72
