Question

the legs of a right triangle have lengths of 4 and 5 units. what is the length of the hypotenuse

Answer 1

This question can be solved using the Pythagorean theorem. $a^2 + b^2 = c^2$ where a and b are the legs of the triangle and c is the hypotenuse.

$4^2 + 5^2 = c^2$
$16 + 25 = c^2$
$41 = c^2$
$\sqrt{41} = c$
So, c is approximately 6.403.
