In a right triangle, one of the angles measures 30 degrees, and the length of the hypotenuse is 12 units.
What is the length of the side opposite the 30-degree angle?
The relationship between the angles and the lengths of the sides in a right triangle is governed by the special properties of 30-60-90 triangles.
You can use the formulas for the side lengths in such triangles, where the side opposite the 30-degree angle is half the hypotenuse.
