You can't. I believe if we're given more details such as length from point A to point B, time, or distance travelled. Maybe it is possible. Can you provide full question?

How to find angle of elevation with given force

The angle of elevation is always measured from the ground up. It is an upward angle from a horizontal line. It is always inside the triangle ABC.

Example:

A tree is 14m high.

The observer stands 30m before the tree.

In the triangle ABC is

the height of tree BC or a,

the distance AC or b,

the angel of elevation BAC or \(\alpha\) .

Then:

\(tan\ \alpha= \frac{a}{b}\\ \alpha = arctan \frac{a}{b}\)

In the example:

\(\alpha = arctan\ \frac{14m}{30m}\\ \alpha =25.017°=25°1'1'' \)

The angle of elevation in the exemple is 25°1'.
