If the side opposite a 60-degree angle in a 30-60-90 right triangle is 7sqrt(3) cm long, how long is the hypotenuse? 1 point) 28 cm 14 cm 7sqrt(3) cm 7 cm
In a 30-60-90 right triangle, the side opposite the 60-degree angle is always sqrt(3) times the length of the side opposite the 30-degree angle. In this case, the side opposite the 60-degree angle is 7sqrt(3) cm long, so the side opposite the 30-degree angle is 7 cm long.
Since the hypotenuse is always twice the length of the side opposite the 30-degree angle in a 30-60-90 triangle, the hypotenuse in this case would be 2 * 7 cm = 14 cm.
Therefore, the correct answer is 14 cm.
