The slope is defined as
![m=\dfrac{\Delta y}{\Delta x}=\dfrac{6-2}{-4-x}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B%5CDelta%20y%7D%7B%5CDelta%20x%7D%3D%5Cdfrac%7B6-2%7D%7B-4-x%7D)
So, we have the follwing equation:
![\dfrac{6-2}{-4-x} = 3 \iff 4 = 3(-4-x) \\\iff 4=-12-3x \iff16=-3x \iff x = -\dfrac{16}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B6-2%7D%7B-4-x%7D%20%3D%203%20%5Ciff%204%20%3D%203%28-4-x%29%20%5C%5C%5Ciff%204%3D-12-3x%20%5Ciff16%3D-3x%20%5Ciff%20x%20%3D%20-%5Cdfrac%7B16%7D%7B3%7D)
Answer:
26.3 cm³
Step-by-step explanation:
![\boxed{volume = \frac{mass}{density} }](https://tex.z-dn.net/?f=%5Cboxed%7Bvolume%20%3D%20%20%5Cfrac%7Bmass%7D%7Bdensity%7D%20%7D)
Volume of the rod
= 200 ÷7.6
= 26.3 cm³ (3 s.f.)

<u>Answer(1):</u>
Law of Cosines.
<u>Answer(2):</u>
since side "c" is missing so we will write formula used for side "c"
![c^2=a^2+b^2-2ab\cdot\cos\left(C\right)](https://tex.z-dn.net/?f=c%5E2%3Da%5E2%2Bb%5E2-2ab%5Ccdot%5Ccos%5Cleft%28C%5Cright%29)
<u>Answer(3):</u>
First lets write both sine and cosine formulas:
Check the attached picture for the list of formulas:
From given picture we see that two angles A and B are missing. Also 1 side "c" is missing.
Sine formula uses two angles while cosine formula uses only one angles.
Hence cosine formula will be best choice to find the missing values.
