A-Level Maths E1-12 [Trigonometry: Find all the Missing Sides and Angles of a Triangle]

So it's basically either a gamble on which angles to use? Or alternatively working out every single possible answer and reinsert them to see if they equate to a set value like a or A? That's hella tedious. But okay. I guess I'd rather work with numbers than be broke later on.

hi. Thanks for the great video. I'm just wondering however, do you reccomend where to find what formulas are provided and what you have to learn for the exam? (I'm learning it by myself to sit as an independent candidate so I'm not sure where to find these things).

can't you just do 180 - the sin answer and it gets you the same thing
