Question

find the value of theta ​

Answer 1

sᴏʟᴜᴛɪᴏɴ

given :

$\sec( \alpha ) \times \sin( \alpha ) = 1 \: \: \: \:$

we know that :

$\sec( \alpha ) = \frac{1}{ \cos( \alpha ) }$

then

$\sin( \alpha ) \times \frac{1}{ \cos( \alpha ) } = 1$

$\tan( \alpha ) = 1$

then , alpha = π/4 = 45°

[ tan π/4 = 1]
