Answer:
1: Supplementary angle; x = 95
2: Complementary angle; x = 31 [(2x-3)+x]
3: vertical angle; x = 90
4: supplementary angle; x = 92 [x+(x-4)]
Explanation:
1: 180-85 = 95 (x)
2: (2x-3)+x = 90 evaluates into x = 31
3: all sides are equal so if one side is 90 then the rest are
4: x+(x-4) = 180 evaluates into x = 92
