**Problem : **
What is the area of Triangle ABC given that *a* = 4, *b* = 7, and *B* = 75^{o}?

sin(*A*) = .5520.

*A* 33.5^{o}.

*C* = 180 - *A* - *B* 71.5^{o}. Area =

13.3.

**Problem : **
What is the area of Triangle ABC given that *b* = 14, *A* = 20^{o}, and
*B* = 120^{o}?

*C* = 180^{o} - *A* - *B* = 40^{o}. Area =

, or
in this case, Area

= 24.9.

**Problem : **
What is the are of Triangle ABC given that *b* = 22, *c* = 15, and *A* = 48^{o}?

Area =

*ab* sin(*C*), or in this case,

*bc* sin(*A*) 122.6.

**Problem : **
What is the area of Triangle ABC?

*C* = 180^{o} - *A* - *B* = 55^{o}. Area =

34.5.

**Problem : **
