Question

एक झील की सतह से x मीटर ऊंचे एक बिंदु से एक बादल का उन्नयन कोण a है तथा झील में बादल के प्रतिबिंब का अवनमन कोण b है तो प्रेक्षण बिन्दु से की दूरी

Answer 1

The distance of the observer from the lake is $\frac{x}{tan A}$.

Step-by-step explanation:

Given:

    The distance between lake and the cloud = x m

  Angle of elevation from observer to cloud = A

Let the distance of observer from the lake be 'y'.

 

According to question,

                 ⇒ tan A = $\frac{x}{y}$

                  ⇒ y = $\frac{x}{tan A}$

There is also a reflection of cloud through lake which is also at same distance which is 'x'. But to find the answer, there is no use of  that to find the answer.
