lol...wat do u need..here

hartnn (hartnn):

1/sin x = 1+ cos x/sin x (theta=x for convenience) sin x +cos x =1 (1/\(\sqrt2\)sin x + 1/\(\sqrt2\)cosx) = 1/\(\sqrt2\) sin (x+ pi/4) =1/ \(\sqrt2\) sin (x+pi/4) = sin pi/4

I am not entirely sure. my answer choices are in degrees 90 270 90,270 no solution

hartnn (hartnn):

even 90 satisfies sin x+cos x =1

hartnn (hartnn):

sin 90 + cos 90 = 1+0 = 1
