If e = 9 cm and f = 40 cm, what is the length of g?





43 cm





31 cm





39 cm





41 cm

Answer 1

That's Pythagorean theorem :-)

If e and f are the shorter sides of the triangle, and this is a right triangle, then the length of the hypotenuse (g, presumably) will be related by \[e^2+f^2 =g^2\]If you solve that for \(g\), by taking the square root of both sides, \[g = \sqrt{e^2+f^2}\]Plug in your numbers and find the answer.
