To clarify the vocabulary a bit.... The measures of the angles are not supplementary -- the angles are supplementary.

Two angles are supplementary if the sum of their angle measures is 180 degrees.

If angle F is 113 degrees and it is supplementary to angle E, then angle E is 180-113 = 67 degrees.

Then since angle D is supplementary to angle E, the measure of angle D is 180-67 = 113 degrees.

ANSWERS: angle D is 113 degrees; angle E is 67 degrees
