Answer 2

Step-by-step explanation:

Correct option is

B

2

Consider the given equation.

sinθ+cosecθ=2

sinθ+

sinθ

1

=2

sin

2

θ+1=2sinθ

sin

2

θ−2sinθ+1=0

(sinθ−1)

2

=0

sinθ=1

Therefore,

cosecθ=

sinθ

1

=1

Now,

sin

9

θ+cosec

9

θ=(1)

9

+(1)

9

=2

Hence, B will be correct answer.

plz mark me brilliant answer.
