An oblique triangle has:
, , and .
Determine the length of side .
The basic relationships among sides and angles of an oblique triangle are given by and .
When three parts (including a side) of an oblique triangle are given, the Law of Sines or the Law of Cosines can be used to solve the triangle.
There are

:
1. One side and two angles are given.
2. Two sides and one opposite angle are given.
3. Two sides and the included angle are given.
4. Three sides are given.
The

is used in cases 1. and 2.
The

is used in cases III and IV.
LAW OF SINES
For any triangle

The sum of all angles is , and we will find third angle

or
or
then
