Question
____________.
Hint:
Alternate angles are equal
The correct answer is:
30
in the given figure,
AB || CD and the line DB cuts the 2 sides at some angle, making <CAB and < ACD 1 pair of alternate angles.
Given, < EAB = 30 degrees.
Using the property of alternate angles, we can say that <ECD = < EAB = 30 degrees.
The alternate angle theorem states that when two parallel lines ( AB and CD) are cut by a transversal (here DB ), then the resulting alternate interior angles or alternate exterior angles are equal
