Answer: The second matrix
If we want to write a proper matrix to represent the given system of equations, we have to arrange it in order:
After this, we can write the matrix with the coefficients of each equation:
![\left[\begin{array}{ccc|c}1&1&1&180\\2&-1&0&0\\4&0&-1&-5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Cc%7D1%261%261%26180%5C%5C2%26-1%260%260%5C%5C4%260%26-1%26-5%5Cend%7Barray%7D%5Cright%5D)
Being this, the matrix that represents the measure of each angle in Ming's triangle
Answer:
To solve a quadratic equation by factoring,
Put all terms on one side of the equal sign, leaving zero on the other side.
Factor.
Set each factor equal to zero.
Solve each of these equations.
Check by inserting your answer in the original equation.

Proof
AC = DB
AB = DC
BC = BC This side is equal to itself and is common to both triangles.
Three sides of one triangle equal to 3 sides of the other means that the triangles are congruent. It is the Theorem you need.
Answer:
A and B
Step-by-step explanation:
Because the surface area is 
BA is the base, so 
also works.
