Question

from the top of a cliff 150 m high the angle of depression of two boats are 60° & 30° find the distance between the two boats (they are on same side)
​

Answer 1

Answer:

Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a system on which is fixed a material called the stationary phase.

Answer 2

BF=(150−x)m.

Let AC=y

tan30°= y/150−x

tan60° = y/150

⇒y=(150−x)√ 3 = 150/√3

∴150−x=50 , x=100 m
