Question

.if sec 15θ = cosec 15θ (0° < θ < 10°) then value of θ is

Answer 1

sec15@=cosec(90-15@)
sec15@=sec(90-15@)
15@=90-15@
15@+15@=90
30@=90
@=90/30
@=3 Ans

Answer 2

Answer:

$\theta=3$

Step-by-step explanation:

Given :$Sec 15 \theta = Cosec 15 \theta$

To Find :$\theta$

Solution :

$sec15\theta=cosec(90-15\theta)$

$sec15\theta=sec(90-15\theta)$

$15\theta=90-15\theta$

$15\theta+15\theta=90$

$30\theta = 90$

$\theta = \frac{90}{30}$

$\theta=3$
