Answer:

sin(sin^-1  1/5+cos^-1  x)=1     ____(1)

We know that ,  sin 90=1

                i.e. sin pie/2=1      ____(2)

Comparing (1) and (2)

      sin(sin^-1  1/5+cos^-1  x)=sin pie/2

(Comparing angles)

      sin^-1  1/5+cos^-1  x=pie/2

                      sin^-1  1/5=pie/2-cos^-1 x

(we know that,

                        sin^-1 x+cos^-1 x=pie/2

                                       sin^-1 x=pie/2-cos^-1 x)

      sin^-1  1/5 =sin^-1 x

                  1/5=x

              i.e.  x= 1/5.  

ALL THE BEST DEAR.
