you might be wondering that how is angle AOP equal to 30 degree.............. frst focus on the triangle AOB........THERE u see angLE ABO is given to be 60 degree...and ABO = OAB(since both angles correspond to the radius sides OA and OB)..........BY USING triangle sum property sum equal to 180 DEGREE u wl get AOB=OAB=60 DEGREE

now focus on the triangle AOP here u have equal sides AP and AB ......USING the property that angle corresponding to the equal to the sides are equal..so angle AOP AND POB are equal.......after this apply angle sum property in triangle APO....U will get angle AOP=POB=30 DEGREE...............REPLY if u have any problem???????????????/

AP= OA sin30 degree AP = OA/2=6/2=3CM
