Final answer:
In a 30-60-90 triangle, if the shorter leg is 8 cm, the length of the hypotenuse is 16 cm.
Step-by-step explanation:
In a 30°-60°-90° triangle, the length of the shorter leg (opposite the 30° angle) is always half the length of the hypotenuse. So, if the shorter leg is 8 cm, the hypotenuse will be twice that length, which is 16 cm.
