Value of AB will be 4cm by Pythagoras theorem
BD will be 2 cm as D is midpoint of AB.
Now applying Pythagoras theorem in triangle BDC where BC=3,BD=2
SO VALUE OF DC WILL BE root13
BD will be 2 cm as D is midpoint of AB.
Now applying Pythagoras theorem in triangle BDC where BC=3,BD=2
SO VALUE OF DC WILL BE root13
Samanwita:
No answer will be only 13...Not root 13
nope it will be root 13
No no
see u have done totally correct but in the last step u have done wrong
recheck ur answer n u will get ur wrong...
how are u getting 13
if it is 13 it will not fit in triangle
See my answer
Otherwise listen
DC square=BC square-DB square...by phythagorus theory....
