thats dumb. u didnt show how you got the 8 ? :s ur correct upto the part where yyou found the height but thats about it....

[WhuupHisBack]

On my math paper it says to find the height (h) and its given the (a) part of a right triangle and but I have to figure out the (b) part of the triangle (aka (h)

[kekelhuvsyhuu]

how did she get that 8m?

[SRR023]

teachers should just teach like this at schools

[haloreachlover99]

this is the sequel of little drunmer boy no madder how many smiles you put on her. she never smiles for real

[terryakiyall]

why is it 72 meters squared and not 72 square meters...is that the same thing?

[joeglimmix]

don't speak bad of her...if you do she will climb out of the computer screen and chase you around your huose like samara

[Tito559a]

Stupid the height is always unkown she Failed

[ThomasBHofSoCal]

...at just after :30, what she means is that the height (also known as the altitude) is not always given in the original diagram of the triangle.

[BekoByBeko]

I can't concentrate too much because of her straight face.. lol ..

[zoomzoom943]

Wow I was so confused on test, If the other two numbers on the sides of the triangle don't matter why the heck do they put them!? lol this helped a lot..

[ytjfogbfnin]

This helped ALOT! thanks:)

This helped ME.

[asdf12831]

I love how the ppl discuss the hotness of the women here shes hot shes not hot and giving shit about what shes saying.. :-D

[tmac9938]

guys who think she's hot need to get laid. besides she writes her 8's backwards.

[ryanz6879]

Are u guys all dumb asses because she is not fuking hot!!!

[lilwin25]

if you post a coment about school and not just some wacky stuff then your cool and care about life but school sucks

[Qermaq]

So we have two right triangles here. One has a hypotenuse of 10 and a side of 8, so the left part of the base is 6. (36 + 64 = 100) That means the other triangle's 2 sides are 8 and 12, and as 64 + 144 = 208, the hypotenuse of that triangle is 14.42... not 14. They lie to us blatantly. They could have used a triangle with base of 14, height of 12, and the two top sides 15 and 13, and the area would be 84, and the math would have been correct. Ugh.

She is cute tho.

[ehasko]

@Qermaq I find her sexy as well!

[zhzhzh5]

and what do u do if all u have is the measure of the sides?

[bracesandfangs]

The teacher looks so scary. ._. I dont feel like learning!!! uwaaah!

[asdf12831]

@bracesandfangs IOI 

[whatsupanime101]

lol they talk like those telephone monetors :P hehe yah that helps alot hehe

[nabilah71]

Very Very Helpfull!!! This Lady always helps me with all math problems!!!!:D:P:)):)

[N05L31]

thanks this helped me on my homework I got stumped

[DogNose3000]

her head looks like a turnip

[lalabri887]

wow ! she scares me , =\ her head distracted me.

[keren092]

what about if you have all the sides but the high is missing?

i need to know..bacause im doing a calculus homework where i have to find the are of a triangle using a method for pre-algebra/algebra, geometry,algebra 2, pre-calculus n calculus for each different method! =(

[trazafindragolo]

did u got ur answer? cuz i need dat too...if u knw the answer how to find the height...please can u tell me?

[keren092]

well...no i had to use a specific formula that i found in the internet....if u use the Pythagorean theorem is more probable that it wont be accurate... cause u can divide the triangle perfectly where the high suppose to be...=/

[trazafindragolo]

i got da answer...ok so if u trace a line in the middle so ur goin to have two triangle...then you goin to use pythaforean theorem...to find the hypotneus.... nd dats the heigh

[trazafindragolo]

i meant if u use pythagorean after tracin the line its easy...nd my bad the hypotneus is not the heigh

[keren092]

well...it worked in ur trianlge cause in mine i couldnt do that bcause if i trace the line my c side gets divide but i dnt know the length of each part....

[dasdasdus]

i am having a problem in geometry how do you get the area of a triangle? if you only know two heigts one 12 cm and the second 10,nothing else

[trazafindragolo]

use the pythagorean theorom...

[Davincy2312]

Don't let any of the people that opposes you hurt you!

You do your work, God bless you and people should appreciate the help they are being given.

:]

[ronaldo10235]

how do you find the 8m in the triangle, or height. when it's not given.

[gangstaz001]

@ronaldo10235 Nobody knows cuz i cant find a vid of it on youtube -.-

[TakesTwoToTango]

put the lower left point of the triangle in (0,0). Construct the 2 circles the upper point has to lie on: x²+y²=10² and (x-18)² + y² = 14². This lets itself solve to x = some number (1st equasion: y² = 100-x², substitute in the 2nd one). Then you have the x-coord of the top point, it's y-coord is the 8m (:= "a"). Pythagoras: x² + a² = 10². You just calculated x (x-coord of the top point of the triangle), so you'll find that a = 8 or -8 (the triangle could be upside down mathematically).

[shadovv24]

@ronaldo10235 if the 8m was not given use the pythagorium therom to figure it out.

[khep24]

@shadovv24 Its not an equalteral triangle so if the base is split it wont be evenly seperated with the angle bisector.

[laxkid922]

thats brutal you robot

[andypiersmorris]

I concur

[gmsherry1953]

One small problem -- as near as I can figure, the height of a triangle having sides 18, 10 and 14 is not 8 -- it's approx. 7.74. So the area is more like 70 than 72. There was really no need to show the 10 and 14 -- they are not used in the problem. But if you're going to show them, you should get it right. Maybe they think rounding to the nearest whole number is close enough. (It caught my eye because hypotenuse of 10 and side of 8 is a 3-4-5 triangle, other side 6. 8-12-14 does not work.

[cutesugerfree]

she look like shes reading what shes talking about

[flookzakub7]

So I want to know about area The sky

[gory1727]

they look like aliens talking

[joelg772]

her voice is so anoying

[kasumisman]

[MapleStoryKillaStab]

i cant find one for grade 6 -_-

[BrutusJones]

Ok ....ooops duh I'm wrong ..... I get it now

[nndth]

[spartacus4x]

Wow, I would hate to be in her class. Annoying inflection.

[X4SleepyMaloX4]

i got it
