right angels are at d and c.. srry if u need any more info just inform me

Actually data given by u is not sufficient
there can be three cases of making triangle DBC right angled
1)Right angled at D
if so BC becomes Hypotenuse then
BC^2=DC^2+DB^2
=>BC=10^(1/2)=3.13
2)Right angled at C
if so DB becomes right angled
then BC=8^(1/2)
3)Cant be right angled at B as BD cant be greater than
BC in that case.

Need more info. Are the triangles the same size? Are the two "Bs" and "Ds" the same angles? Which is the right angle?

if the right angles are at d
then BD is 3
and BC is square root of 8
