Find the missing values

Step-by-step explanation:

We know that the total angle sum of the quadrilateral internal angles is 360° since we are working with a quadrilateral polygon.

So when finding the interior angles we set up the equation  of

Subtract 180 by 125 and 72 to find y and x

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

constants mean the stopped points or the points on a graph that nothing is changing, hope this
