Question: 1. Determine if the vectors a = [-1, 5, 3], b = [-2, 4, 7], and c = [10, 7, 1] are coplanar. 2. Given

 1. Determine if the vectors a = [-1, 5, 3], b= [-2, 4, 7], and c = [10, 7, 1] are coplanar.2. Given a = [4, 7, 1] and b = [-3,1, 5]:

a) Calculate the angle between a and b. b) If c =[3, -4, t], find t so that a and c are perpendicular.Giventhat these are math questions, I personally find solutions that are written
