Question

For different c^(2=A^(2-B^(2 Where c is length of the third side of triangle formed from connecting the head of B to the head of A .
use the sane approch to proved that c=√(A^(2+B^(2-2ab*cosQ)

Answer 1

Explanation:

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.

c= √(a*(3
