Answer:

D cos(N)

Step-by-step explanation:

In case you haven't remembered the fact that the sine of an angle is equal to the cosine of its complement (the other acute angle in a right triangle), you can always go back to the definitions.

Sin = Opposite/Hypotenuse

sin(L) = NM/NL

and

Cos = Adjacent/Hypotenuse

cos(N) = NM/NL = sin(L)

The equivalent of sin(L) is cos(N).

For each pair of points below, think about the line that joins them. For which pairs is the line parallel to the x-axis? Circle

Ksivusya [100]

Answer:

The correct answer is (b).

Step-by-step explanation:

A line is parallel to the $x$ axis if it has a slope equal zero. Then if we compute the slope of the line that joins the points $(3,9), (8,9)$ then

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{9-9}{3-8}=\frac{0}{-5}=0$

This implies that the line which that joins this points is parallel to the x-axis.

Observe that the slopes of the lines corresponding to the other items are nonzero.
