how would you find an angle given 2 side lengths and the area ?
Good question! You would put (1/2 x side 1 x side 2) x sine theta = area
then Divide both side of your working by the part in the brackets.
So you would have sin theta = area divided by (1/2 x side 1 x side 2)
Type into your calculator: Shift Sin (area divided by (1/2 x side 1 x side 2))
Hope this helps! Reply if I didn't make sense...

Can that rule be used on a right angled triangle as well?
