Pythagorus` Theorem

Hey guys stupid homework yet again
anybody good with Pythagorus` Theorem?
im looking to solve a problem like this

-Normal Triagle-
-Left side = 16m-
- Right Side = X -
- Bottom = 11M -




Question is
Calculate the value of X into two decimal places

I SUCK AT THIS

 

which side is the hypotenuse or whatever its called? the 'longest' side.

Its just a^2 + b^2 = c^2 (c being the hypotenuse).

 

yeah usually the a squared + b squared = c squared but i suck at this anyways
the right angle at bottom left of triangle ,, uh hyp is X , longest side is 16m shortest is 11m

 

x= 19.42 if x is the hypotenuse... if not
x= 11.62 if x is the leg

Yeah its 19.42, Cfrey is right. Also a right angled triangle isn't really a 'normal' triangle lol. I don't think i'd classify any triangle as a normal one .

 

thanks guys

 

sorry bout the double post cfrey can you post the working out

 

a²+b²=c²

16²+11²=c²

256+121=c²

256+121=374

√374 = 19.42

x=19.42

Basically you take the 2 numbers you have and square them if its a leg and a base. Then you add those #'s to find c². After you find that number you take the square root of the added number and you get the length for c. c is x in this equation so c=19.42 but you would put x=19.42.

 

its 377, not 374 . 374 would give you a square root of 19.34

 

u guys are bloody legends
i might post another 1 ehhee
