Question

The angle of depression of two ships from the top if light house and on the sameside of itsfound to be 45 and 30 ..
If the ship are 200m apart find the height of the lighthouse

Answer 1

AC is the height of the light house and 45 and 30 degree are the angles of depression . So now angleABC=30 angle ADC =45 degree. Now apply tan theta =opp/adj .so now here tan30= AC/BC ,we knew that the value of tan 30 is 1 by root 3 so we willget it as Bc = 200root 3 .similarly tan45=1 and now CD = 200m.Now here i we add these two we will get 200+200 root 3
