Question

cos a=1/2 and sin b=1/2.find a and b

Answer 1

HEY FRIEND....
HERE IS YOUR ♥ANSWER♥
$\cos(a) = \frac{1}{2} \\ as \: \cos(60) = \frac{1}{2} \\ = > a = \frac{\pi}{3} \\ similarly \: \sin(30) = \sin( \frac{\pi}{6} ) = \frac{1}{2} = \sin(b) \\ = > b = \frac{\pi}{6}$
a=60° and b= 30°
I HOPE IT HELPS YOU...!!!
