Right-triangle problem solving
Knowing one side length plus one more piece of information, like an acute angle or a second side, lets you find every other side and angle of a right triangle using sine, cosine, tangent, and the Pythagorean theorem. For example, if one leg is 5 and the angle across from it is 30 degrees, the hypotenuse is 5 / sin(30 degrees) = 10, and the Pythagorean theorem then gives the last leg. Two angles alone only fix the triangle's shape, not its actual size, so at least one side length is always needed.
