Proponents of the alkaline diet suggest that a diet high in acid-producing foods disrupts the blood's normal pH level and, in turn, triggers the loss of essential minerals (such as calcium) as the body attempts to restore equilibrium. This imbalance is said to increase susceptibility to illness.
The law of cosines is useful for computing the third side of a triangle when two sides and their enclosed angle are known, and in computing the angles of a triangle if all three sides are known.
A generalization of this theorem is the law of cosines, which allows the computation of the length of any side of any triangle, given the lengths of the other two sides and the angle between them. If the angle between the other sides is a right angle, the law of cosines reduces to the Pythagorean equation.
