Answer:

60 degrees is the measure I think... or 90.

Answer:

40

Step-by-step explanation:

In a triangle all the angles equal to 180

DCE=90 because its a right angle

So you know what both the angles are in the triangle 90 and 60

So you Add both of them together- 90+60=140

Then 180-140=40

CED=40 degrees
