In a 45°-45°-90° triangle, equal legs measure 5√2 cm, how long is the hypotenuse?
5 cm
10 cm
15 cm
18 cm
In a 45°-45°-90° triangle, the length of the hypotenuse is equal to the length of one of the legs multiplied by √2.
Therefore, in this case, the length of the hypotenuse is 5√2 cm * √2 = 5 * 2 = 10 cm.
Therefore, the answer is 10 cm.
