cosecA+sinA=x.........(2)

cosecA-sinA=√5

cosecA+sinA=x

----------------------------

2cosecA =√5+x..............(3)

cosecA-sinA=√5

cosecA+sinA=x

-----------------------------------

-2sina=√5-x...........(4)

(3)×(4)

2cosecA×(-2sinA)=(√5+x)×(√5-x)

-(2×2)cosecAsinA=(√5)²-(x)²

-4cosecAsinA=5-x²

-4=5-x²

x²-4-5=0

x²-9=0

x=√9

x=3
