Law of Sines and Cosines; Area of Triangles Mixed Practice WORKSHEET DESCRIPTION
This worksheet provides lots of practice on using the advanced trigonometry formulae. Section A gives questions where learners will need to use the correct formula to find missing lengths of triangles. Section B then asks for missing angles. Section C provides a completion table with gaps to find using all the different methods. Finally, section D gives two bearings problem solving questions.
