Since it is given that \( \Delta LAF \cong \Delta NOW \), the triangles are congruent, which means their corresponding sides and angles are equal in length and measure.
To find the length of \( LF \), we need to look at the corresponding sides of these triangles. For instance, if side \( LF \) corresponds to side \( NW \) in triangle \( NOW \), then the length of \( LF \) would be equal to the length of \( NW \).
However, you haven't provided the lengths or any specific values from the image of the triangles.
If the question includes specific lengths associated with corresponding sides (for example, if \( NW \) or another side has a given length), please provide those values. Without that information, I can't determine the length of \( LF \) accurately.
If any side lengths are equal and you know them from similar images or context, match them to find the length of \( LF \). For example, if you know \( NW = 3 \), then \( LF = 3 \). If you can share those lengths or other details, I can assist you further.
