MACHINE SHOP CALCULATION - OD1640 - LESSON 2/TASK 3
angle, two parts are known (at least one of them being a side).
The two
known parts must be either one of the acute angles and any one of the sides,
or any two sides.
EXAMPLE
Given an acute angle and the hypotenuse in figure 18, find angle B and sides
"a" and "b."
SOLUTION
Here, "a" is the side opposite and "b" is the side adjacent to Angle A.
Angle B = 90,,- A = 46,, 40', which is the complement of angle A. According
