What is the hypotenuse of a triangle with legs that are both 4 inches?

Question

Need help , please help lol I’m in a test and I need it now :|

Answer 1

hypotenuse = 4sqr2 = about 4(1.414) = 5.656 inches

h^2 = s^2 + s^2 = 2s^2

h= sqr(2s^2) = s(sqr2)

h= 4(sqr2) = about 4(1.414) = 5.656... inches
