Answer:
x = 106 degrees
Explanation:
74 plus 74 = 148
360 is the interior angle sum of all trapezoids
360-148=212
212 is the sum of both x and y
x and y are the same measure.
212/2 = 106
106º
Because both the base angles are 74º. The known angles so far are 148º.
The top angles also have to be equal as they are on parallel lines so:
360 - 148 = 212º
212 / 2 = 106º
