Question

If the magnitudes of the vectors A, B and C are 6, 8, 10 units respectively and if A + B = C, then what is the angle between A and B ?

​

Answer 1

Answer:

angle 90°

c Resultant

C=A+B

|a|=6, |b|=8, |c|=10

c=√a^2+b^2+2abcosx

10=√6^2+8^2+2•6•8cosx

10=√36+64+96cosx

10=√100+96cosx

10^2=100+96cosx

100=100+96cosx

100-100=96cosx

0=96cosx

cosx=0/96

cosx=0

cosx=90°

I hope you understand
