14.6
Consider the given diagram.
To find AB we will use the Segment Addition Postulate. We are given that BC= 5.4 units and that ⊙ J has a radius of 10 units. Recall that the diameter is twice the length of the radius, meaning that AC=2 * 10 = 20. We can use this information to find the length of AB.
We have found that AB=14.6 units.
