Answer 7

For the second part of the question, you know the standard inner product of two vectors in euclidian space is : <a, b> = |a||b|cos(theta) where theta is the acute angle between the vectors. you can easily solve for the cosine of the angle. Now for the first part, consider the u's and v's to be like unit vectors in the cartesian plane. Hope this helps!
