Question

the legs of a right triangle are 3 and 4. find the length of the hypotenuse.

Answer 1

write down the general formula which is :\[c^2 = x^2 + y^2\]

Answer 2

For this, you would use the pythagorean theorem:\[ a ^{2}+b ^{2}=c ^{2}\]
Since the legs are 3 and 4, replace a and b with them.
\[3^{2}+4^{2}=c ^{2}\]
9+16=c^2
25=c^2
Take the square root to get c=5

Answer 3

so c is :

\[c =\sqrt{3^2 + 4^2} =\sqrt{25} = 5\]
