Answer:
![R = 10.39^\circ](https://tex.z-dn.net/?f=%20R%20%3D%2010.39%5E%5Ccirc%20)
Step-by-step explanation:
Since you have the lengths of all the sides, you can use sine, cosine, or tangent to find the answer. Let's use the tangent ratio.
For angle C, AB is the opposite leg, and BC is the adjacent leg.
![\tan C = \dfrac{opp}{adj}](https://tex.z-dn.net/?f=%20%5Ctan%20C%20%3D%20%5Cdfrac%7Bopp%7D%7Badj%7D%20)
![\tan C = \dfrac{22}{120}](https://tex.z-dn.net/?f=%20%5Ctan%20C%20%3D%20%5Cdfrac%7B22%7D%7B120%7D%20)
![C = \tan^{-1} \dfrac{22}{120}](https://tex.z-dn.net/?f=%20C%20%3D%20%5Ctan%5E%7B-1%7D%20%5Cdfrac%7B22%7D%7B120%7D%20)
![C = 10.39^\circ](https://tex.z-dn.net/?f=%20C%20%3D%2010.39%5E%5Ccirc%20)
Answer:
the slope of the line shows the rate of change of y relative to x
Answer:
FOr the first one you can do:
y= -x +4
y= -x+2
y = -x
y= -x-2
y = x-4
Step-by-step explanation:
I'll do the second one in a different answer use these for now.
Answer:
x = 3
Step-by-step explanation:
![x + sin^2 \theta + cos^2 \theta = 4 \\ x + 1 = 4 \\ ( \because \: sin^2 \theta + cos^2 \theta = 1) \\ x = 4 - 1 \\ x = 3](https://tex.z-dn.net/?f=x%20%2B%20sin%5E2%20%20%5Ctheta%20%2B%20cos%5E2%20%20%5Ctheta%20%3D%204%20%5C%5C%20x%20%2B%201%20%3D%204%20%5C%5C%20%28%20%5Cbecause%20%5C%3A%20sin%5E2%20%20%5Ctheta%20%2B%20cos%5E2%20%20%5Ctheta%20%3D%201%29%20%5C%5C%20x%20%3D%204%20-%201%20%5C%5C%20%20x%20%3D%203)
