Obviously, you're not opposed to using technology (Brainly) to help you get answers. I find it more direct to use an app or calculator for the purpose.
1. The 4th selection is approximately correct.
2. The 1st selection is correct.
3. The 1st selection is correct (one triangle).
4. The 2nd selection is correct.
5. The 2nd selection is correct.
.. sin(C)/7 = sin(126°)/12
.. C = arcsin((7/12)*sin(126°)) ≈ 28.2°
6. The law of sines can be used to tell you the distance is about 646.4 miles.
.. d/sin(90°+23°) = (146 mi)/sin(35° -23°)
.. d = (146 mi)*(sin(113°)/sin(12°)) = 646.4 mi
