c.
To determine the angle of elevation
The angle of elevation
Given:
The friend’s position with respect to the person is shown as:
And the friend has repelled halfway down the cliff.
Calculation:
The person has repelled halfway down the cliff, so the new height is given as:
Now, calculating the angle
Hence, the angle of elevation
