Question

sin 50° /cos 40°+ cosec 40° / sec 50° - 4 cos 50° cosec 40°


solve this fast ​

Answer 1

Answer:

-2

Step-by-step explanation:

sin 50° /cos 40°+ cosec 40° / sec 50° - 4 cos 50° cosec 40°

=sin(90-40)/cos40+ cosec(90-50)° / sec 50° - 4 cos(90-40)° cosec 40°

=cos40/cos40+ sec50° / sec 50° - 4 sin40° cosec 40°

=1+1-4

=-2
