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°

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
