so guys i was looking up at my drawer and wondered how much of what was up there i could see if i look up up there from below.
Obviously one could see more if one was to stand further away but the amout your able to see wouldnt surpass a certail limit.
to make it easier to imagine i thought of my view as a laser shooting out of my eyes and crossing the cornor of my drawer.
at infinitum the laser relative to the top of my drawer would aproach a certain angle.
Now my question is:
Is there an equasion describing the relation between the hight of laser h and the angle alpha at which it hits the cornor of my drawer at infinite distance?

>inb4 this isnt homework, i didnt even finish high school i was just wondering
