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.
