Chapter 79, Problem 14A

In each of Exercises 11 through 14, three Views of the angular portion of a tool are shown. Do not use cutting and forming tool formulas in solving these exercises. For each exercise:

a. Sketch and label a rectangular solid and the pyramid formed by the angular surface edges. Show the right triangles that contain $\angle A,\angle B,$ and $\angle C$ . Identify the angles.

b. Compute $\angle C$ .

Given: $\angle A=23°00\text{'}$

$\angle B=10°00\text{'}$

a. (sketch)

Use this figure for Exercises 13 and 14.
