\[\sin ^2 x+ \cos ^2 x =1\]
@misssunshinexxoxo
M + N = 90, N = 90 -M cos N = cos (90 -M) =cos 90 cos M + sin 90 sin M cos 90 =0 and sin 90 =1 cos N = sin M
idk what any of that means aha im sorry i had a horrible teacher :(

Answer would be E
No worries let's work it out
Can't be true. If the sin = cos, the angles would both be 45 and sin and cos would be .707
\[(.759)^2+\cos ^2N=1\] \[\cos ^2N=1-.576=.423919\] \[\cos N=\sqrt{.423919}=.651\]
