please help this linear algebra questions with steps ,thanks

Let the three vectors a, b and E be given by . e= ("'31. ll HA I 3'; +173, E=+3, Lad Compute the following quantities: (i) (10 points) The angle between the two vectors ii and 3. (ii) (5 points) The volume of the parallelepiped spanned by the three vectors ii, 5, ii. (iii) (5 points) The projection of 5 onto 5. (iv) (5 points) The area of the triangle spanned by the two vectors 5 and E
