We need to simplify this expression:

So, we will call this expression as:

We can write this equation like this:

So, if we simplify it, this can be written like this:
f(x) = 4 but given that the denominator can't be zero, then:

∴
Therefore:
f(x) = 4 if and only if
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°
