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.
In which c is the side across from angle C. Just like the Law of Sines, the Law of Cosines works for any triangle, not just right triangles. In particular, the Law of Cosines can be used to find the length of the third side of a triangle when you know the length of two sides and the angle in between. To use the Law of Sines to find a third side: 1. Identify angle C. It is the angle whose measure you know.
