Dear student ,let α is angle between A and B then α/2 is angle betwern resultant and A, B now (180-α)/2 is angle between resultant and A,-B is now angle between A+B and A-B is α/2+(180-α)/2= 90

Dear Ishan

It depends on the values of A and B vectors and angle between them. 
for example , when A = B and angle between A and B  is 90 ° 
then angle between vectors A+B and A -B is 90°.
