- In each of the following exercises, the top, front, and right side views of a compound-angular hole are shown. For each exercise, do the following: a. Sketch, dimension, and label a rectangular solid. Within the solid, show the right triangle that contains the hole axis as a side and the angle of tilt. Show the position of the angle of rotation. b. Compute the angle of rotation, R. c. Compute the angle of tilt, T. Compute angles to the nearer minute in triangles with customary unit sides. Compute angles to the nearer hundredth degree in triangles with metric unit sides. All dimensions are in millimeters. a.
