Question

these figures are congruent. what is $m\angle c$?

Explanation:

Step1: Recall congruent triangles property

Congruent triangles have equal corresponding angles.

Step2: Identify corresponding angles

In triangle \(EDC\) and triangle \(UST\), \(\angle C\) corresponds to \(\angle T\).

Step3: Determine \(\angle T\)

Since \(\angle T\) is a right - angle (marked with the right - angle symbol), \(m\angle T = 90^{\circ}\).

Answer:

\(90\)
