Kit folds a bandana diagonally before tying it around her head. The side length of the bandana is 16 in. About how long is the diagonal?

Respuesta :

Folding it diagonally forms a 45-45-90 right isosceles triangle. This type of triangle has lengths of x, x, and x [tex] \sqrt{2} [/tex] The longest side being the hypotenuse, this makes the diagonal 16 [tex] \sqrt{2} [/tex] inches or approx. 22.63 inches
