The easiest way is to write down the length of each side, and then add up
the three numbers.
In fact, that's the ONLY way to find the perimeter. If anything else needs to
be done, that's usually because you don't know all three lengths yet, and
you have to find a missing length. Once you accomplish that, you ALWAYS
find the perimeter by adding them up.

Answer:
<em>r</em>=2<em>p</em>
Step-by-step explanation:
If <em>r </em>is ruler and <em>p </em>is pen, ruler equals pen times 2, so its <em>r</em>=2<em>p</em>
If you are referring to angles of a line, 102° and 78° could be angles of a line since a line equals 180°. This would also be the same for an interior triangle angle and it's matching exterior triangle angle. The two angles (102° + 78°) would also equal 180° since they would be supplementary angles.
I would need to see a picture to know what you are referring to with the 45°.
Hope this helps a little at least! :)
