heyaa friend!!!!
by Pythagoras theorem
AC^2 = AB^2 + BC^2
AC^2 = 36 + 64
AC^2 = 100
AC = 10cm
BN is perpendicular bisector of AC
therefore NC = AC/2 = 10/2 = 5
in triangle BNC
by Pythagoras theorem
BN^2 + NC^2 = BC^2
BN^2 + 25 = 64
BN^2 = 64 - 25
BN^2 = 39
BN = √39
hope this is the correct answer and it helps :)
