I thought the tangent might be FE cause it seems like the only one that crosses the circle once.

OpenStudy (anonymous):

no information about the radius?

OpenStudy (anonymous):

The radius is 4 cm.

OpenStudy (anonymous):

ok,now just check which of the triangles is right (pythagoras) then the segment perpendicular to a radius is a tangent

OpenStudy (anonymous):

its most probably FE

Oh good. I was sorta right. Thanks. CBD is larger than 90 degrees and so is ABG, so yep. :)
