Sinx = 1/4 , in quadrant 2nd

Answer» HOPE u LIKE my process
=====================
= > \sin(<klux>X</klux>) = \frac{1}{4} \\ \\ or. \: \: \sin(180 - x) = \frac{1}{4} \\ \\ or. \: \: 180 - x = \sin ^{ - 1} ( \frac{1}{4} ) \\ \\ or. \: \: 180 - x = 14.47751219 \\ \\ or. \: \: x = 180 - 14.47751219 \\ \\ or. \: \: x = 165.52248781 \\

or, x = 165.52 ° approx.__in DEGREES
\\ or, x =\pi - \frac{23\pi} {50}\\ or, \:\: x = \frac{27\pi} {50}
__In radian__
