Answer:

∠DCE = 67

Step-by-step explanation:

In triangle DCE,

∠DCE + 23 + 90 = 180 (angle sum property)

=> ∠DCE + 113 = 180

=> ∠DCE = 180 - 113

=> ∠DCE = 67

Hope it helps :)

The answer is 67°.

Step by step explanation:

Since all triangles equal 180°

Let x be the value of m∠DCE.

x + 23° + 90° = 180°

x = 180° - 90° - 23°

x = 67°
