Question

In right ∆LMN, sin M = 0.759. What is cos N? 0.121
0.241
0.349
0.651
0.759

Answer 1

\[\sin ^2 x+ \cos ^2 x =1\]

Answer 2

Answer 3

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

Answer 4

idk what any of that means aha im sorry i had a horrible teacher :(

Answer 5

Answer would be E

Answer 6

No worries let's work it out

Answer 7

Can't be true. If the sin = cos, the angles would both be 45 and sin and cos would be .707

Answer 8

\[(.759)^2+\cos ^2N=1\]
\[\cos ^2N=1-.576=.423919\]
\[\cos N=\sqrt{.423919}=.651\]
