Well they have to be perpendicual because they cross and parallel means that they are like lines on lines paper, they do not cross, they just keep going. Hope this helps :)
Answer:
The second one
Step-by-step explanation:
Answer:
![h = \frac{9}{13} c + \frac{612}{13}](https://tex.z-dn.net/?f=h%20%3D%20%20%5Cfrac%7B9%7D%7B13%7D%20c%20%2B%20%20%5Cfrac%7B612%7D%7B13%7D%20)
Step-by-step explanation:
Assuming h depends on c, then the slope intercept form will be:
![h (c)= mc + b](https://tex.z-dn.net/?f=h%20%28c%29%3D%20mc%20%2B%20b)
where m is the slope and b is the y-intercept.
The given expresion is
![6.50h + 4.50c = 306](https://tex.z-dn.net/?f=6.50h%20%2B%204.50c%20%3D%20306)
We subtract 4.50c from both sides to get:
![6.50h = - 4.50c + 306](https://tex.z-dn.net/?f=6.50h%20%3D%20%20-%204.50c%20%2B%20306)
We divide through by 6.50 to get:
![h = \frac{4.50}{6.50} c + \frac{306}{6.50}](https://tex.z-dn.net/?f=h%20%3D%20%20%5Cfrac%7B4.50%7D%7B6.50%7D%20c%20%2B%20%20%5Cfrac%7B306%7D%7B6.50%7D%20)
![h = \frac{9}{13} c + \frac{612}{13}](https://tex.z-dn.net/?f=h%20%3D%20%20%5Cfrac%7B9%7D%7B13%7D%20c%20%2B%20%20%5Cfrac%7B612%7D%7B13%7D%20)
Answer:
C
Step-by-step explanation:
Let us first write an equation. Using the SOHCAHTOA rule, we should know that the tangent of an angle equals it's
. The opposite of our given 20° angle is 9, and the adjacent side is <em>x</em>.
°![)=\frac{9}{x}](https://tex.z-dn.net/?f=%29%3D%5Cfrac%7B9%7D%7Bx%7D)
![0.364=\frac{9}{x} \\x=\frac{9}{0.364}\\x=24.7](https://tex.z-dn.net/?f=0.364%3D%5Cfrac%7B9%7D%7Bx%7D%20%5C%5Cx%3D%5Cfrac%7B9%7D%7B0.364%7D%5C%5Cx%3D24.7)
<u>C</u>
