<em>Exterior Angles:</em>
<u><em>Angles facing outward on a triangle</em></u>
Angles 6, 5 and
4 are not inside the main triangle. They are wide open. <u><em>Exterior simply means the outside of something.</em></u> Angles 6, 5 and 4 are the outside angles to the main triangle.

<span>92.23 Gallons per day. Because you divide 645.6 by 7, so that you can calculate the daily usage. :) </span>
X + 3y= -1
-2x - 6y = 2
These two equations have the same solution because we can see that they are equivalent.
One way to find out is this:-
Since x has a +1 next to it, and the other equation has a (-2) next to the x, we can multiply everything on the first equation by 2 to see if they are equivalent.
x+3y= -1
(-2)*x + 3y*-2 = -1*-2
-2x+ (-6y) = 2
-2x-6y=2
Now we know that both of these equations have the same solution.
