if one vector is 4i, then the other is
3/√2 i + 3/√2 j
so, adding them up, the resultant is
r = (4+3/√2)i + 3/√2 j
|r| = √(25+12√2)
at an angle θ where tanθ = (4+3/√2)/(3/√2) = (3+4√2)/3
3/√2 i + 3/√2 j
so, adding them up, the resultant is
r = (4+3/√2)i + 3/√2 j
|r| = √(25+12√2)
at an angle θ where tanθ = (4+3/√2)/(3/√2) = (3+4√2)/3
