Consider three vectors = (1,2,-2), (3, -5, 1), = (0,-2,3). ==== Part(a)[4 points] Find the area of the triangle formed by the vectors and . Part(b)[3 points] Part(c) [5 points] and Y. Prove that a, b and do not lie in the same plane. Suppose = (a + 1, 6-4, y-1) is perpendicular to both a and b. Find a,
