In a right triangle, the three angles are 30, 60 and 90. What is the ratio of the three sides

The right side of a 30 degree angle is equal to half of the hypotenuse. Remember this? You can calculate it by yourself. Suppose that the right side of a 30 degree angle is 1, then the hypotenuse is 2. According to the Pythagorean theorem, you can calculate another right side. Don't be too lazy. Math needs to be practiced more diligently
