Answer:
I'm not sure
Step-by-step explanation:
Let , the point is o and,
Height of Pillars = h
and Distance between AB = 150 m (here DA and CB are pillars)
So,
Ao = 150 - oB
in Triangle(DAo),
tanD(D = 60)= Ao / DA => √3 = (150- ob)/ h
so, h = (150 - oB) /√3
Similarly in Triangle(CBo)
tanC(C = 30) = oB / CB => 1/√3 = oB / h
so, h = √3oB
By Equating Both h We get,
(150 - oB) / √3 = √3oB
150-oB = √3×√3 oB = 3oB
150 = 3oB + oB = 4oB
oB = 37.5
h = 37.5√3
