Question

A person observes two banks of a river at angles of depression theta 1 and theta 2(theta 1<theta 2) from the top of a tree of height h which is at a side of the river.The width of the rivers is d.Draw the diagram for given situation.​

Answer 1

the required diagram is in the above image

Answer 2

Step-by-step explanation:

Let PQ be the tree situated at one of the sides of the river.

Let R and S be the two banks of the river.

From the top the tree i.e. from point P, the angle of depression at points R and S are $\theta_1\text{ and } \theta_2$ respectively.

It has been given that height of the tree is h and the width of the river is d.

Hence, we have

RS = d

PQ =h

Attached is the diagram of the situation.
