3*2x+1=9*2x-1
6x+1 = 18x-1
-18x = -18x
-12x +1= -1
-12x -2
-2/-12= 1/6
x=1/6 or 0.16

Answer:

∠CED = 48°

Step-by-step explanation:

By adding all angles together, they’ll eventually equal ∠AED. Hence, sum of all given angles = ∠AED

∠AEB + ∠BEC + ∠CED = ∠AED

29°+12°+x = 89°

Solve for x and we will get measure of ∠CED:

41°+x = 89°

x = 89°-41°

x = 48°

Therefore, the measure of ∠CED is 48°
