Answer 3

I am thoughts so far: angle NMP and NPM are known and are same, so PMN can be calculated, since NO bisects PMN, the angle MNO is known. Take the tan of MNO gives you OM/ON, OM is 6cm by construction, so ON is known

Answer 4

the area is 4 time the area of triangle OMN, which is 2*OM*ON

Answer 5

AM = MO = OP = PB = 6 cm
