Question

The magnitude of vectors A ,B,C are 3, 4 , 5 units respectively. If A vector + B vector =C vector. find the angle between A and B vectors.
​

Answer 1

Answer:

90°

Step-by-step explanation:

since it obeys pythagorus theorem

A²+B²=C²

then angle between A and B vectors is 90°

3²+4²=9+16=25=5²
