X=20°

Secondary school geometry..
x=20°
Tell me if you want me to post solution.
(terrible handwriting)

Not sure how this can be classified as 'math'.

This is a variation on the 80-80-20 triangle problem AKA the langley adventitious angles problem (more specifically the 70-60 variation)

Thank you but that's legit method in math world? In school if you use more than one assistant building (draw line) in same section you get zero points in the chapter.

Considering this is one of those famous math challenges, you're allowed to do so.

Nice. At math world too many draw lose theory value or it's just law made to get students to stay on topic?

I'm not sure, I'm not really a geometry guys. Aside from taking calc 3, I dont really remember having to draw anything spectacular.
