Solution

Steps of Construction.
(i) Draw a line BC=6 cm.
(ii) With the help of the point B, draw ABC=120
(iii) Taking radius 3.5 cm, cut BA=3.5 cm
(iv) Join AC.
(v) Draw r bisector MN of BC.
(vi) Draw a circle O as centre and OC as radius.
(vii) Draw angle bisector of ABC which intersects circle at P.
(viii) Join BP and CP
(ix) Now, BCP=30.
