Question

add vector A B and C each having magnitude of 100 unit and incline to the x-axis at angle 45, 135 and 315 respectively

Answer 1

Hint :

Resolve the vectors in the x and y - axis direction with proper signs. That would make it easier to add them. Then, just add all the x - components of vectors and j - components of vectors.

Solution :

Vector A = (100 cos 45°) i + (100 sin 45°) j.
Vector B = (-100 cos 45°) i + (100 sin 45°) j.
Vector C = (100 cos 45°) i + (-100 sin 45°) j.

Add all these, and you will get your answer.
