LOL SCIP Can you pls explain to me why that couldn't be the correct answer if the ratios between those two triangles is 2:3 then it's not gonna be right triangle either way 5.3^2 + 6^2 is not 9^2 3x8/2 = 12 6^2+9^2 = 12^2 you can have an ratio between right triangles wat are you talking about scip you'll just get square roots everywhere
wtf
6^2+9^2 = 36+81=117
12^2 = 144
?? 6 9 12 is not a right triangle, not even close lol

wait wat
soniv said oh yeah 6 9 12 triangle so i assumed it was a triplet i forgot about
rekt
the smarter answer then is that you need a calculator to calculate 16/3 and you don't for 12 lel

edit: I'm not sure where in my mind I thought 6/9/12 was a right triangle

you don't need a calculator to calculate 16/3, not over here in continental europe

you have to realize you are twice the intended age bracket
and european so its like 4x intelligence

In my mind, the 5.33 answer is better because it makes the picture less wrong. It's not a right triangle, but at least the smaller pictured triangle is smaller and and longest pictured side is the longest one.

How in the hell do people have the disposable income to throw $100 at a time at people streaming who you could watch for free, and who are doing ABSOLUTELY NOTHING BUT PLAYING GAMES THEY'D BE PLAYING ANYWAY
People doing speedruns, people playing Isaac, DotA, LoL....I get following so if you like a guy for whatever reason you can see when he/she gets online and shit but subscribing/donating...I dunno I guess I'm just cheap or something but I don't get it. People have money and they want to support what they like. maybe wave is mad because no one likes him Hey I like Wave. I just don't watch his streams at all because he doesn't stream anything that I care to watch. He still has a sexy awesome voice though. + Show Spoiler +Hey sweet I'm a Firebat now. Slammin' I forget if you answered this, but what DO you like? All I remember is the stuff you don't 
You did ask me this and I DID respond. It was a nice and long answer too, I'm glad it made such an impression.
;_;
Basically when it comes to things that I watch, I'd put myself down for mostly fighting games and Warhammer 40k Dawn of War II replays. I'll watch other things as well, but those are the ones I watch the most.
Of course the things that I watch and the things that I play are two different categories. I'll happily watch someone play some game that I do play, but I do like watching fighting games and DoWII because I suck at fighting games and the caster for DoWII replays is probably the best caster I've ever seen. Ever.

I guess you do need a calculator to calculate 16/3 over in US hahaha
Dude, it doesn't matter whether you say it's 5.33 or 12, the picture is wrong either way and it's not right triangle either way. It's not about critical thinking in any way it's just a shitty picture making the question unclear.

How? The picture leads you to believe it's a right triangle(and that the 'smaller' one is the larger one), that's exactly what I take issue with in my post.
Edit: Ya I don't know why I used 6.333, it's 5.33xxx and 6.7xxx and I guess I mixed them up. Should've just gone with 16/3.

except if you mean 6 1/3 is 5 1/3 means that 5 1/3 is incorrect when theres no reason why it is if the ratio is in the opposite direction

Despite this math problem showing how little many of us can do basic math, I'm glad that my anger was justified.
Thank you friends.

5 1/3 would still not be correct if you're assuming a right triangle(because you used the picture as your reference, which is why you worked the ratio as 2:3;A:8), because there can't be a 5.333, 6, 9 right triangle.

there also can't be a 12, 6, 9 right triangle, whats your point?
if it was a right triangle we wouldn't need the other trinagle for anything because of pythagoras' theorem

the picture isnt wrong, 90 degree angles have a special notation. If it is absent, then it is not 90 degrees, even in grade school

So you're saying you instantly caught on to the picture being misleading because the second triangle was there at all? My instinct was just that there was extra information present(or that the kids don't know Pythag's yet), but that I would still just solve it that way. It wasn't until I realized that working in either direction(3:2 or 2:3) worked with pythag's that I considered the picture was incredibly retarded and neither are right triangles.
Maybe you're just more intelligent than me, I suppose that's what you're fishing for.

You know what, that's actually true, and I'm far more ashamed about missing that than anything else now.
