This problem has been solved! The width (or height) of the crate – the distance straight across from the base to the other side – could vary depending on the inside angles of vertices A, B, C and D. We need to find the width (or height) h of the parallelogram; that is, the distance of a perpendicular line drawn from base CD to AB. Thus, we can use the sine function.
Does the answer help you? Is the hypotenuse of the right triangle formed when we draw the height of the parallelogram. Check the full answer on App Gauthmath. Image transcription text.
