Answer:
The measure of angle C is 
Step-by-step explanation:
we know that
If AB || DC
then
-----> supplementary angles by consecutive interior angles
and remember that the sum of the interior angles in a trapezoid is equal to 360 degrees
step 1
Find the measure of angle D
substitute the measure of angle A
step 2
Find the measure of angle C
substitute the values
