with what?
Step-by-step explanation:
Answer:graph B
Step-by-step explanation:because if a line is parallel they have no solutions with a certain slope
If two lines intersect then they must have at least a solution
X is 180 - 30 = 150,
The sum of the sides of a polygon is the (number of sides - 2) * (180) so the total interior angle measure of the right polygon is 360.
360 = 80 + 90 + 150 + y
x = 150
y = 40
