The hypotenuse of an isosceles right triangle is 8.4 in. Find the length of a side.
Find the length of a side to the nearest tenth of an inch.
Because it is an isosceles triangle, both of the sides are the same length, x.
x^2 + x^2 = 8.4^2
2x^2 = 70.56
x^2 = 35.28
x = 5.9 inches, rounded we can forget about the negative root
