#1: 99 Quadrilateral angles = 360°/360-94-87-80=x

#2: 17 triangle angles = 180°/180-112-51=y

#3: 46 transversal alt. int. angles congruent/46 alt. int. = 46

#4: 93 linear pairs = 180°/180-87=93

#5: 122 triangle angles = 180°/180-37-21=122

#6: 8 triangle angles = 180°/180-112-60=8

#7: 96 linear pairs = 180°/180-84=96

#8: hexagon hexagons have six sides/six sided polygon being tessellated=hexagon

#9: AAS AAS = two angles then one side are congruent/two angles+one side=AAS

#10: 72 int. angle of a regular pentagon=108°: +ext. angle=linear pair/180-108=72
