The isosceles trapezoid ABDE is part of an isosceles triangle ACE. Find the measure of the vertex angle of ACEA: 130 B: 60C: 65D: 50
Accepted Solution
A:
You can solve this problem by folllowing the steps below:
1. Draw a segment from the point C to the line AE, as you can see in the figure attached. 2. You have now two equal right trapezoids, then: m∠ABG=m∠EDG. 3. m∠ACE=m∠EDG 3. The sum of the interior angles of the trapezoid is 360º. 4. Then, you have:
