I,ve just started vectors & oblique triangles. Without any instruction thus far, can anyone explain this begining process problem? 6.o cm, 150degrees; 1.8cm, 315 degrees. draw the given vectors &find their sum graphically. magnitude is first, followed by direction as angle in standard position. 2d & it is two problems two answers, I apologize, it was one question. I just started this chapter after trig functions of any angle and this is also my first time on this site. I hope I haven't posted wrong.
