Do you know what you're doing after you find the missing side with sine rule

[rigid flax]

Which is what

|| cosine rule ||

[rigid flax]

u dont need the missing side

[gray raven]

U can do it with sine only

[rigid flax]

u can use sine rule to work it out

its just messy

[gray raven]

Equate both sides

And u get surds over surds

For x
