Question
In any angle ABC prove that the perimeter = a/Sin A(Sin A + Sin B + Sin C)
Start with perimeter = a+b+c
but b= aSinB/sinA and
c= aSinC/SinA
and if you don't remember, a=a=a*SinA/
SinA
Start with perimeter = a+b+c
but b= aSinB/sinA and
c= aSinC/SinA
and if you don't remember, a=a=a*SinA/
SinA
