5^2 + 17^2 = 314

sqrt(314) = 17.72004515

Good job!

So the Hypotenuese, being C would equal

the square root of 5 squared + 17 squared

which equals 17.72004515

So your right

Note : Pythagorean Therom only works on right triangles. not Isosoles or Scalene

B ” (17 x 17) = 314

C ” = 339

Square root of 339 = 17.720045

a^2+b^2=c^

where:

a and b is the sides

C is the hypotenuse

5^2+17^2=x^2

25+289=x^2

get the squareroot of both sides, which will leave x

so x is the squareroot of 314

5^2 + 17^2 = X^2

square them and add them, then get the square root to get X

so,

5 ^ 2 + 17^ 2 = X ^ 2

25 + 289 = X^2

X = square root of 314

X = 17.7200451

So the answer is your answer is right.

Its the square root of 25+ 17^2

5×5 + 17×17 = x squared

25 + 289 = x squared

= 314

square root of 314 = 17.2

5^2 + 17^2 = x^2

x = sqrt[314] = 17.72 …
