Step 1
First, let's find the vectors AB and AC: AB = (3.0, 1) - (2.1, -1) = (0.9, 2) AC = (-1.3, 2) - (2.1, -1) = (-3.4, 3) Show more…

A parallelepiped has one vertex at the origin O. The other endpoints of the three edges that meet at the origin are, A = (2, 2, 1), B = (1, 2, 2), and C = (1, 1, 4). (The figure below is not to scale.) (a) Find the coordinates of the vertex D shown in the figure. (b) Find the angle ∠AOB at the vertex O. (c) Find an equation of the form ax + by + cz = d for the plane containing the points O, B, and C. (d) Find the volume of the parallelepiped.
