Question

Paige was trying to calculate the missing side of a right triangle. she knows that the hypotenuse is 8.2 inches and the length of one side is 5.7 inches. she attempted to solve the problem three times and got three different answers. which of her attempts is correct

Answer 1

$a^2+b^2=c^2$
c = 8.2
a = 5.7
b = missing side
$(5.7)^2+b^2=(8.2)^2$
$32.49+b^2=67.24$
$b^2=34.75$
$\sqrt{34.75}=5.895$
