Answer 2

Answer:

Correct option B

Step-by-step explanation:

To get the exact answer we need to put the trignomatery functions.

Given:x = secA - tanA and y= cosecA + cotA

Find: Need to find the values of the x

Calculation:

$xy=(sec{A}-tan{A})(sec{A}+cot{A})\\xy+x-y+a= sec A.cosec A+cosec A-sec A-1\\=(1/sinAcosA)-(sinAcosA)-(cos A/sin A)\\=0\\xy+x-y+a=0\\x(y+1)y-1\\x=y-1/y+1$
