MACHINE SHOP CALCULATION - OD1640 - LESSON 2/TASK 3
b.
When two angles and the included side are given (figure 28, view B, on
the following page), the area can be obtained from the following formula:
Substituting in the formula given in 15a, above, the following is obtained:
c.
When three sides are given, the following formula is used where a, b,
and c are the three sides and A = 1/2 (a + b + c), then
16.
Conclusion
This lesson served to describe the processes for converting linear
measurements from the English to metric system and from the metric to the
English system, and for solving problems using ratio, proportion, and
trigonometry. These mathematical
