A line with arrow heads at both its ends tangentially intersects the circumference of a circle at a single marked point labeled upper F. The center of the circle is marked by point upper A, which connects to a separate circumference point: upper J.

If FI
is tangent to the circle A
at point F
, AF=28
mm, and ∠FAJ=39
degrees, then what is the measure of FI
?
