Let XY be a tangent to a circle, and let be a XBA secant of the circle, as shown below. If AX = 16 and XY = 8, then what is AB?
Let XY be a tangent to a circle, and let be an XBA secant of the circle, as shown below. If AX = 16 and XY = 8, then what is AB?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
XY2 = XB * AX
82 = XB * 16
XB = 4 AB = 12
I think the answer is 9.6
