In the figure, ?FAB = 30° , ?CAB = 66° , ?GAD = 23° , BA ? EA and G and F are collinear.
(a) What is the measure of ?DAE?
(b) Name three pairs of supplementary angles in this figure.
(c) Name all of the pairs of complimentary angles in this figure.
(d) Name two adjacent angles in this figure.
(a) 90° - 30° = 60°, 60° + 23° = 83°, 180°- 83° = 97°,?DAE = 97°
