In the diagram below, line AB is parallel to line CD. The measure of
∠∠ABC is 28° and the measure of ∠∠EDC is 42°. Find the measure of∠∠CED. Explain why you are correct by presenting an informal argument that uses the angle sum of a triangle.

Answer:

CED=110

Step-by-step explanation:

ab and cd are ll

so abc is equal to bcd (alt. int. angle)

sum of tri comes it bc a tri= 180 just subtract 42 and 28

Answer:

ced is 110 degrees

Step-by-step explanation:

because ECD is 28 degrees and 28+42=70 and a triange always = 180 degrees so it would have to be 110
