The cofactors of each entry in the first row of the matrix are
Ac_11 = -13
Ac_12 = 44
Ac_13 = 27
We have to determine the cofactors of each entry in the first row of the matrix.
Therefore the cofactors of each entry in the first row of the matrix are
Ac_11 = -13
Ac_12 = 44
Ac_13 = 27.
A set of numbers is arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.
Machines had to find a way to cut themselves off from the truth in order to understand humans. Neo's sole purpose in the Matrix is to prevent machines from evolving into dinosaurs.

The slope is 1/0, and that equals 0.
Answer:
6.13
Step-by-step explanation:
Using Sine Law we know that
Using your figure let's assign sides and angles:
A=? B = 60° C = 70°
a = 5 b = ? c = x
If we put that into our formula:
Notice that we have too many unknowns. We need to complete at least one ratio to do this, so how do we do this?
Notice we have 2 angles given, so we solve for the third angle. The sum of all angles in any triangle is always 180°
∠A + ∠B + ∠C= 180°
∠A + 60° + 70° = 180°
∠A + 130° = 180°
∠A = 180° - 130°
∠A = 50°
Now we can use this to solve for x.
So the closest answer would be 6.13
Complementary angles, sum = 90
So 3y - 4 + 73 = 90
3y + 69 = 90
3y = 21
y = 7
Answer
y = 7
