Answer:
129.8 approximately
Step-by-step explanation:
So this sounds like a problem for the Law of Cosines. The largest angle is always opposite the largest side in a triangle.
So 11 is the largest side so the angle opposite to it is what we are trying to find. Let's call that angle, X.
My math is case sensitive.
X is the angle opposite to the side x.
Law of cosines formula is:

So we are looking for X.
We know x=11, a=4, and b=8 (it didn't matter if you called b=4 and a=8).



Subtract 80 on both sides:


Divide both sides by -64:

Now do the inverse of cosine of both sides or just arccos( )
[these are same thing]

Time for the calculator:
X=129.8 approximately
Answer:
there are 35 mg's of sodium/salt and 24 g's of sugar, therefore there is 67.2 packets of sugar and 9450 packets of salt
Step-by-step explanation:
im sorry if its wrong, it is what the calculator said!
I'm pretty sure its 100 because if she gave each of her 19 students 5 invitations that equals 95. (19×5=95) And She had 5 leftover equals 100. (95+5=100)
Try going for B because do 8 times 0.50 and 0.25 times 33 = to 12.25
If u just want the quick answer it’s -i bc i^14=-1 and i^16=1
