Question

Represent a force of 10 Newtown in South​

Answer 1

For reference,

I have taken vector A=10N, vector B=8N, the angle between vectors A & B as

θ (theta) = 60 degrees.

The resultant vector is C and at an angle ø (phi) with vector A.

I have taken ø between vector A and C. If I need to know the angle between vector B and C, say angle α (alpha)

a = tan^-1 A sin0/B+A cos 0

or just a = 60 degrees - 0

Hope that helps.
