Question

Can someone please help??
In right ∆LMN, sin M = 0.759. What is cos N?
A) 0.121
B) 0.241
C) 0.349
D) 0.651
E) 0.759

Answer 1

Answer 2

We ave the \[\large sin(M) = 0.759\]

So that means

\[\large sin(M) = \frac{opposite}{hypotenuse}\]

so lets draw that in the triangle

Answer 3

Now, we want to know \[\large cos(N) = ?\]

We know \[\large cos(N) = \frac{adjacent}{hypotenuse}\]
Well, lets draw what 'cos' would be in the triangle...



What do we notice?
