Answer:

Step-by-step explanation:

first, you have to recognize that the two angles will be the same. They are like that b/c of how they are opposites. next , b/c they are the same , set them equal to each other and then solve the equation for x ( isolate x)

29 = 4x -1

29 + 1 = 4x -1 + 1

30 = 4x

30/4 = 4x /4

7.5 = x

now to find ∠DCE just plug in x, but you also can just observe that ∠DCE is going to be 29° b/c the angle opposite of it is also.
