Question

ar
Given that Ā+B+C = 7. Out of these three vectors
two are equal in magnitude and the magnitude of
the third vector is v2 times that of either of the
two having equal magnitude. Then the angles
between vectors are :
(1) 30°, 60°, 90°
(2) 45°, 45°, 90°
(3) 45°, 60°, 90° (4) 90°, 135°, 135°
