Answer:
Answer:1m = 180 110 = 70
2x = 180 132 = 48
3x = 180 111 = 69
4m = 180 54 = 126
5y = 180 (180 121) 36 = 85
6m = 180 (180 101) (180 123) = 180 79 57 = 44
7y = 180 EQ \F(180 50,2) = 180 65 = 115
8x = EQ \F(360 (180 99) (180 125),4) = EQ \F(224,4) = 56
9x = 360 (180 62) 122 = 1208y = x = 120y = EQ \F(120,8) = 15x +
y = 120 + 15 = 135
10a = 360 (180 31) 95 = 1162b = a = 116b = EQ \F(116,2) = 58a +
b = 116 + 58 = 174
