In the diagram below, angle, B, \cong, angle, B, A, D, \cong, angle, A, D, C∠B≅∠BAD≅∠ADC and m, angle, A, D, E, equals, 80, degrees, .m∠ADE=80 ∘ . Find m, angle, C, .m∠C.
Solution
In this problem, you're working with a geometric diagram where multiple angles are congruent, and you're asked to find the measure of . Here's a step-by-step approach:
-
Given information:
- , which means these three angles are congruent (equal in measure).
- , meaning the measure of angle is 80 degrees.
-
Triangle : The triangle has angle , and the sum of all interior angles in any triangle is always 180 degrees.
-
Finding the other angles in triangle : Let's say the measure of angle is , then the sum of the interior angles of triangle is: Thus:
-
Congruent angles: Since , the measures of these angles are equal. If you know or assume any relationships between the diagram's structure or additional angle information, you can proceed to calculate .
Without the exact diagram, these steps outline how to approach the solution. Could you confirm the diagram's structure or provide additional details? I’ll assist further based on that.
