Need Help With Chapter 5 Sine And Cosine Rule (1 Viewer)

[partymaster01]

First things first lol

What mode do we need to set our calculators on

Also i cant seem to get these questions right ... like some of them turn out right and others just don't match the answer no matter what i try.

Any help would be great please.

Calculators should always be set to degrees. Have you ever learned anything about radians?

Are you using a graphic calculator? If you are, it will be reset before the start of the exam. Make sure you go to the settings and change radians (default) to degrees.
