the answer is C
short explanation: the two triangles are congruent so that would make BD equal to AC and if AC is 6 then BD is 6
hope this helps

The triangles AEC and BFD are similar because of AA similarity postulate.

Angles C and D are congruent
Angles E and F are congruent so are
Obs:
Angles A and B since the sum of all angles in any triangle is 180 degrees.

If the triangles are their sides are in proportion.

BD/AC= DF/CE so
BD/6= (6+2)/(6+4)
BD= 6•8/10=4.8

Answer B) BD=4.8
