If sin x = cos $(2x – 10^\circ)$, find the Value of x.
If sin x = cos $(2x – 10^\circ)$, find the Value of x.
यदि sin x = cos $(2x – 10^\circ)$, हो , तो x का मान ज्ञात कीजिए।
Detailed Solution & Logic
$33.33^\circ$
दिया है:
$\sin x = \cos(2x - 10^\circ)$
हम जानते हैं कि
$\cos \theta = \sin(90^\circ - \theta)$
तो,
$\cos(2x - 10^\circ) = \sin(100^\circ - 2x)$
अब समीकरण:
$\sin x = \sin(100^\circ - 2x)$
⇒ या तो $x = 100^\circ - 2x$
$3x = 100^\circ$
$x = 33.33^\circ$
सही उत्तर:
$33.33^\circ$
