Question

PLZ HELP!!! I HAVE AN EXAM!! Find cscΘ if sinΘ=
`(-2)/(7)` and theta is between 180 to 270 THANK U!!

(with explanation pls)

Answer 1

`\boxed{\bold{\red{csc\theta=-(7)/(2)}}}`

`\large{\red{Solution\: given:}}`

`Sin\theta=(-2)/(7)`

we have

`cosec \theta=(1)/(Sin\theta) =(1)/((-2)/(7))\\=-(7)/(2)`
