Step 1:

\

The two angles of the triangle are \"\"\"\" and one side \"\".

\

The sum of the three angles in a triangle is \"\".

\

The third angle of the triangle  \"\".

\

\"\"

\

\"\".

\

Step 2:

\

The law of sines:

\

If \"\" is a triangle with sides \"\" and \"\", then \"\".

\

Consider  \"\"

\

Substitute \"\", \"\"and \"\".

\

\"\"

\

\"\"

\

\"\"

\

\"\".

\

Step 3:

\

Consider  \"\"

\

substitute \"\", \"\" and \"\".

\

\"\"

\

\"\"

\

\"\".

\

Solution:

\

\"\", \"\" and \"\".
