pls mark as branliest

Answer 2

Answer:

√2

Step-by-step explanation:

I used x instead of theta :

therefore,

tan6xtan4x=1

or, sin6x sin4x = cos6x cos4x

or, 2sin6x sin4x = 2cos6x cos4x

or, cos2x - cos10x = cos2x + cos10x

or, 2cos10x= 0

or, cos 10x= 0

or, 1-2sin²5x=0

or, 2sin²5x= 1

or, sin²5x= 1/2

or, cosec²5x=2

or, cosec 5x= √2
