Answer:

  B.  56

Step-by-step explanation:

The exterior angle 72° is half the difference of the intercepted arcs, 200° and x:

  72° = (200° -x)/2

  144° = 200° -x

  x = 200° -144°

  x = 56°

1. What is the value of x? Show all of your work.
asambeis [7]
AB^2 + BC^2 = AC^2
AB^2 + 6^2 = square root 117^2
AB^2 + 36 = 117

Now subtract 117 from both sides
AB^2 = 81
AB = square root 81 = 9
\sqrt{81}  = 9
Therefore AB is 9 cms.
