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
