We know that sec x=cosec(90-x)
So,
15x = 90-15x
=>30x=90.
=>x=3
So, theta is equal to 3 degrees.
So,
15x = 90-15x
=>30x=90.
=>x=3
So, theta is equal to 3 degrees.

sec15θ = cosec15θ
we know,
secx = cosec(90° - x ) use this here,
sec15θ = cosec(90° - 15θ)
then,
cosec(90° - 15θ) = cosec15θ
90 - 15θ = 15θ
90° = 30θ
θ = 3°
