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.

what is the measure of ∠∠CED is ? And Explain why ?

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

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
