A vector is given as \overrightarrow{ {\A}=4 \hat{i}+7 \hat{j}. What would be the angle, the vector \overrightarrow{ {\A} makes with y-axis

Correct Answer is : θ=Cos−1(7√65)

\theta={\Cos}^{-1} ( {7}/{\sqrt{11}})

\theta={\Cos}^{-1} ( {4}/{\sqrt{11}})

\theta={\Cos}^{-1} ( {7}/{\sqrt{65}})

\theta={\Cos}^{-1} ( {4}/{\sqrt{65}})
