the length.of a hypotenuse of a right triangle is 32 inches and the length of one of the lrgs is 18 inches. what is the length,

Elza [17]

Let: hypotenuse = a , known leg = b , unknown leg = c
According to Pythagoras' Theorem: $a^{2} = b^{2} + c^{2}$
   $c^{2} = a^{2} - b^{2}$
   $c^{2} = (32 inches)^{2} - (18 inches)^{2}$
c = $\sqrt{(32 inches)^{2} - (18 inches)^{2}}$
c = 3.74 inches

∴ the length of the hypotenuse to 1d.p. ≈ 3.74 inches
