To find the measures of angles D and G, we can use the properties of complementary and supplementary angles.
We are given that angle D is complementary to angle E. Complementary angles add up to 90 degrees. So, if angle E measures 78 degrees, angle D can be found by subtracting 78 from 90.
Angle D = 90 - 78
Angle D = 12 degrees
We are also given that angle D is supplementary to angle G. Supplementary angles add up to 180 degrees. Since angle D measures 12 degrees, we can find angle G by subtracting 12 from 180.
Angle G = 180 - 12
Angle G = 168 degrees
Therefore, the measure of angle D is 12 degrees and the measure of angle G is 168 degrees.
