find the measure of the \\( \angle a e c \\) that is supplementary to \\( \angle a e d \\) in the diagram below. enter only the number.
the solution is

Explanation:

Step1: Recall the definition of supplementary angles

Supplementary angles sum to \(180^{\circ}\). So, if \(\angle AED = 65^{\circ}\), and \(\angle AEC\) is supplementary to \(\angle AED\), then \(\angle AED+\angle AEC = 180^{\circ}\).

Step2: Solve for \(\angle AEC\)

Using the equation \(\angle AEC=180^{\circ}-\angle AED\). Substitute \(\angle AED = 65^{\circ}\) into the equation: \(\angle AEC=180 - 65\).
