Question

these figures are congruent. what is ( mangle d )?

Explanation:

Step1: Recall congruent triangles property

Congruent triangles have equal corresponding angles.

Step2: Identify corresponding angles

Since \(\triangle ECD\cong\triangle IJK\), \(\angle D\) corresponds to \(\angle K\).

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

From the second triangle, \(\angle K = 58^{\circ}\).

Answer:

\(58\)
