Hi kev, how do you know which formula to use

[@FreddyPhokungoane]

For sin you need 2 sides and one angle or 2 angles and 1 side. For cosine rule You need 2 or 3 sides and 1 included angle. For area you 2 sides and 1 included angle Hope this helps😊

How can the x square come out of the bracket

[@menzisaclown]

It was x² before Using the cosine rule on triangle ABC b²= a² + c² -2ac.cosB b²= x² + x² -2x².cosB b²= 2x² -2x².cosB Factorise b²= 2x²(1-cosB) b= x[2(1-cosB)]½
