If you look at the problem definition, it says it's a 3-4-5 triangle, since element 1 is 1m (corresponding to the 4 in 3-4-5), L2 is 1 / 4 * 5 = 1.25m. Also in 3-4-5 triangles, the angles are always the same, this is how he got the angle between the local and global x axis of the 2nd element.

I go through all of your videos. all are excellent sir.. thank you for this valuable informations.
how did you get the angle between local and global x axis of 2nd element?
Alos, how did you get L2= 1.25 m?
