here OA perpendicular so it measure is let X
so 2X=180
X=90 so it is the value of vector OB
so 2X=180
X=90 so it is the value of vector OB
zxcbnm:
OB is 4m
it is OA
but as wrong answer is posted already
so no chance now
OB is 4m
boda the question to fund vector OB
yes and OB is of magnitude 4
so I have to find the angle of OB
question demands OB not angle
thank you
