2. Substitute into the first equation and solve for "y" in order to find the y-intercept of the first line:
Knowing that first line passes through the points and
, you can graph it.
3. Substitute into second equation and solve for "x" in order to find the x-intercept:
4. Substitute into the second equation and solve for "y" in order to find the y-intercept of the second line:
Knowing that second line passes through the points and
, you can graph it.
The solution of the system of equations is the point of intersection between the lines. Therefore, the solution of this system is:

120°.
Step-by-step explanation:
The sum of all interior angles in a polygon with sides (
,
) is equal to
. (Credit: Mathsisfun.)
The polygon here has 6 sides. . Its interior angles shall add up to
.
Consider the properties of a regular polygon. (Credit: Mathsisfun.)
- All sides in a regular polygon are equal in length.
- All angles in a regular polygon are also equal.
There are six interior angles in a polygon with 6 sides. All six of them are equal. Thus, each of the six interior angle will be
.
