In algebra, terms are the values on which the mathematical operations take place in an expression. A term can be a constant or a variable or both in an expression. In the expression, 3a + 8, 3a and 8 are terms. Here is another example, in which 5x and 7 are terms that form the expression 5x + 7.
We can calculate a side of a triangle if the side's opposite angle, another side and its opposite angle are known using the Sine rule: a/sin(A) = b/sin(B) = c/sin(C)
