Question

What is the measure of angle CED?

m, because ABC~EDC

m/2 because ABC =~DCE

m + 60 degrees, because ABC-DCE

120 degrees,because ABC=~DCE

Answer 1

m, because abc is similar to edc

Answer 2

Hi there!

Angle CED would be the same as Angle M. This is because triangles ABC and EDC are congruent. Since these triangles are congruent, you can use CPCTC to determine that Angle CED is congruent to Angle CAB, which has the value of M.

Hope this helps!! :)
