Since ACD is equal to 82, then DCE would equal 41. This is because it is half of 82.

Answer:

(A)41°.

Step-by-step explanation:

We know that in Kite, the diagonals are the angle bisectors, therefore

In Kite ABCD, m∠ACD=82°, thus

[tex]m{\angle}DCE=\frac{1}{2}m{\angle}ACD[/tex]

Substituting the given value, we have

⇒[tex]m{\angle}DCE=\frac{1}{2}(82^{\circ})[/tex]

⇒[tex]m{\angle}DCE=41^{\circ}[/tex]

Therefore, the measure of m∠DCE is 41°.

Hence, option A is correct.
