Answer:
Angle B = 90 degree
Because,
The larger side is AC = 12cm
Therefore, apply pythagorean theorem
AC^2 = AB^2 + BC^2
12^2 = ( 6 root 3 )^2 + 6^2
144 = 108 + 36
144 = 144
In the pythagorean theorem, if LHS = RHS then the angle opposite to the larger value of the side should be 90 degree, According to Converse of pythagorean theorem studied in class 10

Step-by-step explanation:
Draw a line BC=6cm
2. Construct 30
o
at B. Extend BP.
3. Take 3.1cm on compass, cut an arc on BP. Join CX.
4. Take perpendicular bisector of CX. It intersects with BP at A. Join AC
