Answer:
x = 50°
Step-by-step explanation:
Angles in a quadrilateral add to 360°
First work out the interior missing angle
360° - ( 40° + 80° + 110° ) = 130°
Angles on a straight line add to 180° so
180° - 130° = 50°

Step-by-step explanation:
Use the distance formula to determine the distance between two points.
The slope-intercept form:

m - slope
b - y-intercept
We have the slope m = -1 and the point (-1, 3). Substitute:

<em>subtract 1 from both sides</em>

<h3>Answer: y = -x + 2</h3>
