I get that r=b^2/a from the triangle similarity.

>thinks using XD meme arrows makes makes what he says is funny
>goes in /wsr/ to not help people

Why is this board so full of pretentious cunts?

>>231497
>Being this buttblasted

>Uses XDD
Are you fine kid? :^)

All I'm say is why not help OP rather than insult him, but you go straight for the "you mad?" Response. Your rebuttal is on the same level of calling someone a cuck mid argument because your out of ideas

>Using cuck
Found the cuck.
Nice try OP

>sees cuck used in a sentence not directly aimed at him.
>uses cuck as an actual insult because that's his natural response.

Next you'll be saying it's bait because that's the only way out of this situation without resorting more insult.

Also I'm not OP you'd notice if you looked at the number of posters

>>231507
>Using reaction images
>Thinks somebody take him seriously
>Has to shitpost on his computer and phone at the same time to defend himself

You're the textbook definition of reddit migration from r/4chan to /b/, maybe lurk for a few more years and your shit posting will improve

I'm not that guy, but telling people to pay attention to class is the best way of helping them with their homework. Too often people use this board to ask the most basic stuff, sometimes it's stuff you can find a few pages into your book, some other times it's stuff you can find in a 15 minute long Youtube video; the fact that they ask here hoping for a free answer and not even bothering to show their current procedure just shows how little effort they put on learning. For example, the hippie with the gross hair could've stated what exactly he does and doesn't understand and he would've gotten useful replies; instead he just wants the full problem solved, which will have to wait a few hours because most people won't bother doing that much. Then when he gets the answer he goes away having learned that this place is a service to get your homework done without even bothering to look it up yourself.

For reference, I'm not that much into math, but after looking it up 5 minutes I could find a Youtube video that showed me exactly how to solve that kind of problem; the real problem is that people are too retarded and just want to be spoonfed. Polite sage.

Good point, generally I just assume people post here as more of a last ditch attempt for help, but suppose you're right there will be some who exploit the help of others
