Answer:
in triangle ABC,<B=90
AB=5cm,<ACB=30
sin 30= opposite side to <C/hypotenuse
1/2=AB/AC
1/2=5/AC
AC=10cm
cos 30= BC/AC
root 3/2=BC/10
10*root 3/2=BC
BC =5*root 3

length of AB is given as 5 in the qn
length of AC can be found out using trignometric values
tan30=5/AC
1/2=5/AC
AC=10
length of AC can be found out using trignometric values
tan30=5/AC
1/2=5/AC
AC=10
