Adding all of these should equal to 180 from the way the angle is set up.
So the equation should be:
(3x + 2) + (2x + 5) + (2x - 9) = 180
You can remove parentheses as it doesn’t affect the equation since it is all addition.
Let’s first add the common variables together.
3x + 2x + 2x = 7x
2 + 5 + (-9) = -2
So now we should have:
7x - 2 = 180
Now add 2 to both sides.
7x = 182
Divide both sides by 7 to isolate x.
x = 26
So x is 26.
Sorry what what is the question?
<h3>Answer:</h3>
The Slope is 
<h2>Explanation:</h2>
Notice that both the points, 
and 
, are on the line. So we can use those points to calculate the slope. Recall that that slope of the line 
can be calculated by 
if we have the points, 
and
