Answer 3

Do you mean they may not APPEAR to be Right Angles? If they are not Right Angles, why are you using the sine function?

Answer 4

I don't know, I'm using the sine rule.

a/sinA = b/sinB = c/sinC

Answer 5

Why? It seems a tangent would be more appropriate.

Answer 6

The course I'm doing is about the sine rule. :/
