Question

In a right triangle ABC, AB, the side opposite the 30 degrees angle measures 12 inches. Which is the length of the BC, the side opposite the 90 degrees angle?

Answer 1

24

Answer 2

in a 30-60-90 right triangle the short side is half of the hypotenuse

Answer 3

if you double the triangle you will have an equilateral triangle since each angle will be 60 degrees, then when you cut it in half you will see that the short side is half of the hypotenuse
