How to find csc theta where theta equals -120

Step-by-step explanation:

Cosec of -120 is to be found out

We can do this in steps

cosec (-120) consider only the - sign.

This implies angle lies in IV quadrant and hence cosec is negative

cosec (-120) =-cosec (120)

Now 120 is written as 180-60

cosec (-120) =- cosec(180-60)

=-cosec 60

(since II quadrant cosec is positive)

=

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
