Answer:

We have, cosec A = 2

Now, sin A = 

⇒ sin A = 

We KNOW that sin² A + cos² A = 1

⇒ cos² A = 1 - sin² A

⇒ cos A = √(1-sin² A)

⇒ cos A = √{1- }

⇒ cos A = √(1 - )

⇒ cos A = √()

⇒ cos A = 

We know that tan A = 

⇒ tan A = 

⇒ tan A = 

We need to find  + 

Substituting the VALUES of each trigonometric FUNCTION obtained EARLIER, we get:

+  =  + 

=  + 

=  + 

= 

= 

=  × 

=  = 8-6= 2
