Find all solutions for a triangle with C=130 degrees, c=17, and b=5.
Round to nearest tenth.
-------------
Use the Law of Sines::
sin(B)/5 = sin(130)/17
----
sin(B) = (5/17)sin(130)
----
sin(B) = 0.2253
---
B = arcsin(0.2253) = 13.02 degrees
-------
-------
Solve for "a":
a/sin(A) = 17/sin(130)
a = 0.6015*17/0.7660 = 13.35
