Question

cosec (90-A)=sec (2A-36) find A​

Answer 1

Answer:

answer A is 12

Step-by-step explanation:

cosec(90-A)=sec(2A-36)

secA=sec(2A-36)

sec get cancelled

A=2A-36

36=2A+A

36=3A

A=36÷3

A=12

please follow me

Answer 2

cosec (90-A)=sec (2A-36) find A​

I hope that angles here are  in degrees

 1).cosec(90-A) = Sec(2A-36)

   implies  

sec(90-A) = Sec(2A-36)

assuming  both quantities as positive ( it doesn't effect )

2). we know ,  Secant  is positive in first and fourth quadrant

 2A).     So for first quadrant

A=2A-36      this gives us A = 36

2B).    for fourth quadrant

   360-A=2A-36    this gives us   A = 132
