Question

What is the length of line segment BC

Answer 1

BC = 1

Explanation:

Frm the diagram

AB + BC = AC , substitute values

x + 16 + x + 6 = 12

2x + 22 = 12 ( subtract 22 from both sides )

2x = - 10 ( divide both sides by 2 )

x = - 5

Thus

BC = x + 6 = - 5 + 6 = 1

Answer 2

BC = 1

Explanation:

AB = x + 16

BC = x +6

AB + BC = AC

x + 16 +x + 6 = 12

x + x + 16 + 6 = 12

2x + 22 = 12

2x = 12 - 22

2x = -10

x = -10/5

x = - 5

BC = x + 6 = - 5 + 6 = 1
