volleyballlover55 · Answer

how would you use it to find a missing side or missing hypotenuse of a right triangle?

@welshfella

rayep12 · Answer

$$a ^{2}+b ^{2}=c ^{2}$$

welshfella · Answer

use the pythagoras theorem

rayep12 · Answer

$$c ^{2}$$ would be the hypotenuse

welshfella · Answer

- as rayep has written 
c will be the hypotenuse, which is the longest side.

volleyballlover55 · Answer

ohhh... wait but its asking how would you use the pythagorean theroem to find a missing side or missing hypotenuse of a right triangle?

volleyballlover55 · Answer

can you like explain it to me in steps please so i understand :)

rayep12 · Answer

lets say u have $$2^{2}+3^{2}=c ^{2}$$

volleyballlover55 · Answer

ok...

rayep12 · Answer

u would multiply 2*2 then 3*3

rayep12 · Answer

then add the product of them together to get 13

rayep12 · Answer

then you would take the square root of 13 like this

rayep12 · Answer

$$\sqrt{13}$$

rayep12 · Answer

and that would be ur answer unless it is a perfect square like 1,4,9…

welshfella · Answer

if you are given the length of  the hypotenuse and one of the other sides you still use pythagoras;

say c = 13 and b = 12 
we have

13^2 = a^2 + 12^2

subtract 12^2 from both sides

13^2 - 12^2 = a^2
169 - 144 = a^2

a^2 = 25 

I'll leave you to find length of a -  You take the square root.

@welshfella hi sorry I had to leave.. but im back.. :)

welshfella · Answer

ok so what is the square root of 25?
