Expert Answer:
so we are given DB=16m
PDB=30 and
CPD = 60
tan30 = 1/3 = PB / BD = PB /16 ==> PB = 16/
3 m
AB = 2PB = 32/3 m
In triangle PCD ,we know CPD = 60 and PD =
(BD2+PB2)
PDC = 90 -
PDB = 60
so PCD will also be equal to 60 i.e. PCD is a equilateral triangle.
so CD will be equal to PD = 32/3 m
