Write a complete two-column proof for following information:

given: segment ab = x + 16, segment bc = 4x + 11
segment ac = 77
prove: ab = 26

Given:

AB = x + 16

BC = 4x + 11 

AC= 77

We can safely assume that,

AB + BC = AC

x + 16 + 4x + 11 = 77

5x + 27 = 77

5x = 77 - 27

5x = 50

x = 

x = 10

Hence, 

AB = x + 16 = 10 + 16 = 26

Hence, proved.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
