For a polygon with n sides, the interior angles add up to:
(n - 2) x 180
an octagon has 8 sides:
(8 - 2) * 180 = 6 * 180 = 1080
from the question,1 side measures 2x while 7 sides measure x. this means
7x + 2x = 1080
9x = 1080
x = 1080/9
x = 120°
if x=120°
2x=2(120°)=240°
so, the seven smaller angles are 120°. while the one larger angle is 240°
This equation is linear, which means that it goes up by the same amount every time you increase X by one.
The general form of a linear equation is <span>y=m∗x+b</span>
where m is the slope and b is the y-intercept. The y-intercept indicates where the equation starts at x=0. In this case, it's 250, meaning that buying the commercial slot cost $250.
m, on the other hand, is the slope of the graph. Here we have 100, meaning that it costs $100 per second to run the commercial. This can be visualized like so:<span>y(0)=100∗0+250=250</span><span>y(1)=100∗1+250=350</span><span>As you can see, the cost went up by $100 after one second.
In general, the slope represents the amount added per time, whilst the y-intercept represents the initial amount.</span>
