The angles of a quadrilateral measure 80 degree, 100 degree, 100 degree and 80 degree in this order. what kind if quadrilateral has this shape? how do you know?

the angles of a quadrilateral measure 80 degree, 100 degreethe angles of a quadrilateral measure 80 degree, 100 degree

Step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer: 7
