Question

Please help!!!!!!!!

sec(x−20°)=cosec(x−20°)

What is x in degrees?

Answer 1

we know that sec theta = cosec( 90 - theta )

sec( x - 20 ) = cosec ( x - 20 )

cosec( 90 - ( x - 20 ) = cosec ( x - 20 )

cosec ( 90 - x + 20 ) = cosec ( x - 20 )

- x + 20 = x - 20

2x = 40

x = 20

hope it helps

Answer 2

Answer: 13

Its 13 because when you do the question it ends up being 13 degrees
