Answer:
x=36
Step-by-step explanation:
These angles added together equal 180 degrees
2x + 3x =180
5x = 180
x = 36
The augmented matrix is,

We have given system of linear equation is,

<h3>What is the meaning of augmented matrix?</h3>
In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.
So, the first row is

the second row is

and the third row is

Therefore the augmented matrix for this linear system is,

Answer: Infinitely many solutions
Step-by-step explanation:
The lines is on top of each other so this makes it many solution.
It can't be NO solution because the lines are not parallel to each, which means they will not intersect.
It can't be one solution because the lines doesn't intersect.
It can't be two solutions because the lines never intersect and they never intersect twice either.
