Question

△ced ≅ △xyw. what is m∠x?

Explanation:

Step1: Use the property of congruent triangles

Congruent triangles have corresponding angles equal.

Step2: Identify corresponding angles

Since \(\triangle CED\cong\triangle XYW\), \(\angle X\) corresponds to \(\angle D\).

Step3: Find the measure of \(\angle X\)

Given \(m\angle D = 78^{\circ}\), so \(m\angle X=m\angle D\).

Answer:

\(78\)
