Can someone ? ?
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

E) 0.759

Explanation

sin = opposite /hypotenuse

cos =  adjacent / hypotenuse

M + N = 90°

sin(M) = cos(90 - M)

90° - M = N

∴ sin M = Cos N

 cos N = 0.759

Option E). 0.759

Step-by-step explanation:

In the given right angle triangle LMN, sin M = 0.759.

We have to find the value of cos N.

Since sum of all angles of a triangle = 180°

Therefore ∠L + ∠M + ∠N = 180°

Since ∠L = 90°

Therefore ∠M + ∠N = 90°

Or N = 90 - M

Now by taking cosine on both the sides.

Now cos N = cos (90 - M)

cos M = sin M [ As we know cos (90 -M) = sin M ]

cos M = 0.759

Therefore option E). 0.759 is the answer.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
