Add vectors A,B and C each having magnitude of 100 unit and inclined to the X axis at angles 45, 135 and 315 degrees respectively. if you can show me how its solved in video representation,that will be appreciated because in your video lectures, you teach how to solve questions with two vectors only. here this question has three vectors in it.
