Question

Sec 15 theta = cosec 15 theta then theta is ?

Answer 1

$\textbf{Answer :-}$

_____________________________

Given :-

sec15Θ = cosec15Θ

To find :-

The value of Θ. [ • Where , 0°≤ Θ ≤ 90° ]

Salutation :-

sec15Θ = cosec15Θ

cosec ( 90° - 15Θ ) = cosec15Θ

[ • As we know , cosec ( 90° - Θ ) = secΘ ]

90° - 15Θ = 15Θ

90° = 15Θ + 15Θ

30Θ = 90°

Θ = 90° / 30

Θ = 3°

•°• The value of Θ is 3°
