two force of 20N and 34N act on a body in such a way that they make an angle of 35 with each other. find the resultant of the two force

Answered by Steve
Using the law of cosines, and the fact that adjacent angles of a parallelogram are supplementary,

r^2 = 20^2 + 34^2 + 2*20*34 cos35°
r^2 = 2670
