Answer:

The answer to your question is: 111°

Step-by-step explanation:

The sum of the interior angles of a polygon is (n - 2) 180°

This polygon has 7 sides

Then n = 7

Process

120 + 158 + 126 + 125 + 121 + 139 + x = (7 - 2)180

120 + 158 + 126 + 125 + 121 + 139 + x = 5(180)

789 + x = 900

x = 900 -789

x = 111°

Answer:

Step-by-step explanation:

We have the following system

$\left[\begin{matrix} 4 & -2 \\ 2 & 1 \end{matrix}\right]x =\left[\begin{matrix} 8 \\ 2 \end{matrix}\right]$

The number of solutions depend on the determinant of the matrix of the system. If the determinant is different from 0, then it has one unique solution, if it 0 then it has infinite solutions.

Note that the determinant of a matrix

$\left[\begin{matrix} a & b \\ c & d \end{matrix}\right]$ is ad-bc. So in our case we have 4*1-(-2)*2 = 8 which is not 0. Then the system has an unique solution.
