for the base = 4units, how do we know if 4units is from c1 to c2 for c1 to point B
how to know whether we need to find the length of the line or we can just use units
there was one question where i used units to solve but ended up with a wrong answer as it required us to find the actual length to continue solving the question

It’s from point B to one of the points labelled C. Those are just two possible positions of C for the question, but I included them in a single diagram.
For each case the base of the triangle will be 4 units long.

As far as I can, I use units to solve the question. This is especially so when a point lies further down a line. Say AC is three times the length AB and these three points are on a line. In such cases, to find C, I will use unit comparisons to do measurements as compared to lengths which may complicate numbers with the decimals.
btw what is angle of inclination?
are you free to take at look at some questions today as i have quite a few questions that i need help with, but if you are not free today then its ok

Angle of inclination, sometimes called the angle of elevation, is the angle at which something is raised from a horizontal line
