I have no clue. im on that same question
Answer:
The third side is around 58.043
Step-by-step explanation:
Use the law of cosines: ![c^2=a^2+b^2-2abcos(C)](https://tex.z-dn.net/?f=c%5E2%3Da%5E2%2Bb%5E2-2abcos%28C%29)
Plug in the two sides we know (into a and b) and the angle we know (into angle C).
Thus:
Use a calculator:
![c^2=3369\\](https://tex.z-dn.net/?f=c%5E2%3D3369%5C%5C)
![c=58.043087...](https://tex.z-dn.net/?f=c%3D58.043087...)

Answer:
the download cost for a song is $1 and $11 for a movie
Step-by-step explanation:
According to the questions, the following equations are as follows:
Let us assume the song be x
And, the movies be y
So,
20x + 13y = $163.........(i)
13x + 13y = $156........(ii)
Now solve substract second equation from the first equation
7x = $7
x = $1
And the y value is
20 + 13y = $163
13y = $163 - $20
13y = $143
y = $11
Hence, the download cost for a song is $1 and $11 for a movie
Answer:
yes
Step-by-step explanation:
if it ends at 430 he will have 30 min before his appoionment
