Answer:
6
Step-by-step explanation: think of it this way. When you adding a positive to a negative, you simply taking the negative away from the positive. So in this case, you are subtracting 2 from 8 to get six. Or, its the difference between the positve and the negative!! Hope this helps!
It should be 2 but i’m not positive
Answer:
![x\approx7.8](https://tex.z-dn.net/?f=x%5Capprox7.8)
Step-by-step explanation:
In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:
![sin(\theta)=\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
![sin(23^\circ)=\frac{x}{20}](https://tex.z-dn.net/?f=sin%2823%5E%5Ccirc%29%3D%5Cfrac%7Bx%7D%7B20%7D)
![20sin(23^\circ)=x](https://tex.z-dn.net/?f=20sin%2823%5E%5Ccirc%29%3Dx)
![x=20sin(23^\circ)](https://tex.z-dn.net/?f=x%3D20sin%2823%5E%5Ccirc%29)
![x\approx7.8](https://tex.z-dn.net/?f=x%5Capprox7.8)
Therefore, the length of the opposite side is about 7.8 units
