If |\overline{a}|=11,|\overline{b}|=23 and |\overline{a}-\overline{b}|=30, then the angle between the vectors \overline{a} and \overline{b} is

Correct Answer is : θ=π−cos−1(125253)

\\theta=\cos ^{-1} ( \frac{253}{125} )

\\theta=-\cos ^{-1} ( \frac{253}{125} )

\\theta=-\cos ^{-1} ( \frac{125}{253} )

\\theta=\pi-\cos ^{-1} ( \frac{125}{253} )
