Question

cosec(65+theta) - sec(25-theta)

Answer 1

cosec(65+∅)-sec(25-∅)
cosec(90-(25+∅))-sec(25-∅)
sec(25-∅)-sec(25-∅)
0

Ans=0

Answer 2

Answer:

Step-by-step explanation:

Cosec [90-(25+theta)] - sec(25-theta)

Sec(25- theta) - sec(25-theta)

So, both will cancel out☝️☝️

And our answer will

=0
