Cos A = (b^2 + c^2 − a^2) / 2bccos A = (10.4)^2 + (29.2)^2 − (22.2)^2) / (2 x 10.4 x 29.2)cos A = (108.16 + 852.64 − 492.84) / 607.36cos A = 0.77 m<A = cos−1(0.77)
m<A = 39.6
from here....you're already known the answer is C.
because only m<A = 39.6
but if you want to make sure you get it right, so you'll calculate another angle...
cos B = (a^2 + c^2 − b^2) / 2accos B = (22.2)^2 + (29.2)^2 − (10.4)^2) / (2 x 22.2 x 29.2)cos B = (492.84 + 852.64 − 108.16) / 1296.48cos B = 0.9544 m<B = cos−1(0.9544)
m<B = 17.4
So now you know for sure answer is C.
Hope it helps
Divide both sides of the given equation by -3. This will give you |x-3| = 2.
Then either x-3=2, resulting in x= 5, or
-(x-3) = 2, or x-3 = -2, resulting in x=1
The solutions are {1,5}.
The answer is 6 tbh wit u

Answer;
In the first column, 35 chickens, and 6 horses.
In the second column, 7 chickens, and 20 horses.
In the third column, 27 chickens, and 10 horses.
In the fourth column, 19 chickens, and 14 horses.
In the fifth column, 37 chickens, and 20 horses.
P.D. Do you need the reasoning or just the answers?
