Answer 2

Let AB is the light house. So AB = 75

From triangle ABC,

tan 45 = AB/BC

=> 1 = 75/BC

=> BC = 75

Again from triangle ADC

tan30 = AB/BD

=> 1/√3 = AB/(BC + CD)

=> 1/√3 = 75/(75 + CD)

=> 1/√3 = 75/(75 + CD)

=> 75 + CD = 75√3

=> CD = 75√3 - 75

=> CD = 75(√3 - 1)

So the difference between ships is 75(√3 - 1) m
