U5D3 HW Textbook Solutions Ambiguous Case

Note: my solution to number 12 is not the most efficient solution as I was demonstrating the typical “ambiguous case” solution. It is more efficient to use ITT (Isosceles Triangle Theorem) once you find the first acute unknown angle.

NOTE: Some answers may be in a different form — with the denominator a rational number.
Example: 1 divide by root 2 can be written as root 2 over 2. If you multiply the numerator and the denominator both by root 2 it makes the denominator a rational number.
You can leave it in either form.
If you change root 2 over 2 to a decimal and 1 over root 2 to a decimal, you will see they are both about 0.7071
I prefer the form: 1 over root 2 for this work.
