what is a?????

anonymous · Answer

im thinking the a that is given is the side length so maybe you have to use it inorder to find the angle???

mayankdevnani · Answer

which side???

anonymous · Answer

well, if this is euclidian geometry, you do 180=A+B+C, wich leads to A=70.

mayankdevnani · Answer

@annie_f    euclidean geometry states that a=bq+r where $$0 \le r < b$$

anonymous · Answer
