Could someone help me solve this q please

A lens of focal length 13.0cm is used to focus an image of the sun. If the incident rays are coming at an angle of 15.0∘ to the optical axis, what is the distance of the image from the optical axis?

Have you drawn a diagram?
If you do, you should see that the answer is just a matter of trigonometry, with an angle and a length given.
