Question

I have no idea how to do this, if you could give me an idea of how to at least do the first one, I think I can do the 2nd myself.

Answer 1

Given:

The angles SWT and WTR are formed as shown in the given figure.

To find: The angles of elevation and angle of depression.

Step-by-step explanation:

We know that,

The angle is formed by the line of sight and the horizontal plane for an object above the horizontal is the angle of elevation.

So, the angle of elevation is,

`\angle SWT`

The angle is formed by the line of sight and the horizontal plane for an object below the horizontal is the angle of depression.

So, the angle of depression is

`\angle\text{WTR}`

Final answer:

`\begin{gathered} \text{An angle of elevation: }\angle SWT \\ \text{An angle of depression: }\angle\text{WTR} \end{gathered}`
