Solve the following triangle
C=80 degrees b=7 and A=45 degrees what is a,c and B
-----
Solve for "B":
B = 180-(80+45) = 55 degrees
-------
Solve for "a":
a/sin(45) = 7/sin(55)
a = [sin(45)/sin(55)]*7
----
a = 6.043
----------------------
Solve for "c":
c/sin(80) = 7/sin(55)
c = [sin(80)/sin(55))*7
c = 8.416
