I am writing theta as 'a'

cos 9a=sin a

cos 9a=cos (90-a)

cos cuts

9a=90-a

9a+a=90

10a=90

a=90/10

a=10

tan 6a

tan 6*10

tan 60=√3


daksh050: your process is ❌
parthomsarwade: how
daksh050: because 90 divide by 10= 9
daksh050: see you have written 10
parthomsarwade: oh by mistake
daksh050: Now can you send me correct solution
