In the diagram below, AB is parallel to CD. What is the value of x?

120 degrees

Step-by-step explanation:

If the lines are parallel to one another, the the opposite corners will be equal in value.

x° = 120°

Step-by-step explanation:

when a transversal line crosses two parallel lines, the alternate interior angles are equal; therefore 120° = x°

step-by-step explanation:

no of data

divide by no of mode

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
