Answer:

cosec (810°) = 1

Step-by-step explanation:

cosec (810°)

We know that any angle greater than 360 = angle - 360x

= cosec (810 - 360x)°              

[Where x is the highest possible value in which the equations evaluates to >= 0]

We can clearly see that 2 is the highest x value for which the equation evaluates to >= 0

= cosec (810 - 360*2)°

= cosec (810 - 720)°

= cosec (90)°

We know that cosec θ = 1/sin θ

= 1/sin (90)

We also know that sin (90) = 1

= 1/1

= 1

∴ cosec (810)° = 1

Hope this helps! If it does, please feel free to mark it the brainliest! Thanks :D
