Supplementary angles add to 180 degrees. If A and B are both supplementary to C, the two angles must be congruent since A=B=180-C.
1st: 100 - 60 = 40
2nd: 94 - 54 = 40
difference between the ranges : 40 - 40 = 0

Answer:
(-4, -1)
Step-by-step explanation:
-3x - 8y = 20; y = 5x + 19
y = 5x + 19; -3x - 8y = 20
y = 5x + 19
-3x - 8y = 20
-3x - 8(5x + 19) = 20
-43x - 152 = 20
-43x - 152 + 152 = 20 + 152
-43x = 172
-43x / -43 = 172 / -43
x = -4
y = 5x + 19
y = (5)(-4) + 19
y = -1
