Answer:
s=13
Step-by-step explanation:
![As\ we\ know\ that,\\"The \ sum\ of\ all\ angles\ of\ a\ triangle\ is\ 180"\\Hence,\\(4s+9)+(3s+1)+(6s+1)=180\\4s+3s+6s+9+1+1=180\\13s+11=180\\13s=180-11\\13s=169\\s=13](https://tex.z-dn.net/?f=As%5C%20we%5C%20know%5C%20that%2C%5C%5C%22The%20%5C%20sum%5C%20of%5C%20all%5C%20angles%5C%20of%5C%20a%5C%20triangle%5C%20is%5C%20180%22%5C%5CHence%2C%5C%5C%284s%2B9%29%2B%283s%2B1%29%2B%286s%2B1%29%3D180%5C%5C4s%2B3s%2B6s%2B9%2B1%2B1%3D180%5C%5C13s%2B11%3D180%5C%5C13s%3D180-11%5C%5C13s%3D169%5C%5Cs%3D13)
Option D:
Segment DF
Solution:
Let us first define the relationship between the side and angle in triangle.
<u>Relationship between the side and angle in triangle:</u>
- The shortest side is always opposite to the smallest interior angle.
- The largest side is always opposite to the largest interior angle.
To find the largest side in ΔDEF:
Largest angle in ΔDEF is ∠E = 73°
So, the side opposite to 73° is DF.
Therefore, Option D is the correct answer.
Hence the segment DF is the longest side in the ΔDEF.
