Based on the definition ofadjacentandnonadjacent angles, we have:a. <DEF and <FECb. <AED and <AEBc. <LMJ and <AEDd. <KML and <CEFWhat are Adjacent Complementary Angles?Adjacent complementary anglesare two angles that share a common side and together add up to 90 degrees (a right angle).What are Adjacent Supplementary Angles?Adjacent supplementary anglesare two angles that share a common side and together add up to 180 degrees (a straight angle).a. One pair ofadjacent complementary anglesis: <DEF and <FEC, because 60 + 30 = 90 degrees.b. One pair ofadjacent supplementary anglesis: <AED and <AEB, because they both form a straight line which equals 180 degrees.c. A pair ofnonadjacent anglesthat arecomplementaryis: <LMJ and <AED, because 50 + 40 = 90 degrees.d. A pair ofnonadjacent anglesthat aresupplementaryis: <KML and <CEF, because 150 + 30 = 180 degrees.Learn more aboutadjacent Complementary angleson:brainly.com/question/2681537#SPJ1...
