Hello guys !! it s deep here

Hey guys, yesterday we learnt the information about sin law and cosine law.here are the some of them formulas that how we can find the sides of traingle and angles of traingle.

to find the sides and the angles here are the some of the formulas

a2 =b2 +c2-2bc cosa

b2=a2 + c2 -2ac cosb

c2=a2+b2 -2ab cos

this is the cosine law
