Answer:

\text{cos}(M)=\frac{19}{20}

Step-by-step explanation:

Please find the attachment.  

We have been given that in right triangle LMN, L and M are complementary angles and \text{sin}(L)=\frac{19}{20}. We are asked to find the \text{cos}(M).

We know that sine relates opposite side of right triangle to hypotenuse.

\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

We also know that cosine relates adjacent side of right triangle to hypotenuse.

\text{cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}

We can see from the attachment that LM is hypotenuse and MN is adjacent side of our given triangle.

\text{cos}(M)=\frac{19}{20}

Therefore, \text{cos}(M) is \frac{19}{20} as well.

What is an equation of the line that passes through the points (-6, -5) and (-6, -2)?
Fittoniya [83]

Answer:

x=-6

Step-by-step explanation:

The x coordinates are the same,  so we know that we have a vertical line.

Vertical lines have no slope, so they are in the form

x=

Since the x coordinate is -6

x=-6

Answer:

6.04 inches.

Step-by-step explanation:

Corbin want's to make a model, in which every 100 feet would be shown by 1 inch.

The monument is 604 feet in height.

Divide 604 with 100:

604/100 = 6.04

The height of Corbin's model would thereby be 6.04 inches.
