Question

36. From the top of a 75 m high lighthouse from the sea level, the angles of depression of two ships are 30° and 45°. If the ships are on the opposite sides of the lighthouse, then find the distance between the two ships.​

Answer 1

Step-by-step explanation:

height of the light house = 75m

angle of depression is 30 and 45 degree

therefore use tan 45 to find the ground distance

now substitute the value and find the distance between the ships using tan 30

the distance comes out to be 100√3-100

100(√3-1) meters

now put the value of √3 if given
