Still don't get it /:
Is there an equation I have to do?

so DC / m = m / AC
and DC = 5 and AC = 19

similar triangles have the same shape
that is corrsponding angles are aequal
in the diagram < BDC = <ABC
<ACB = <DCB
so other angls are also equal

2
so going back to the formula
5 /m = m /19
m^2 = 5*19 = 95
so m = sqtt 95
(Option B)
