The first option because turn them all into degrees and it says:
54, 60, 90, 120, 255
y+43°= 180°( straight angle)
=>y= 180°-43°

Answer:
abc = - 126
Step-by-step explanation:
(2x + 3)(3x - 1) ← expand product using FOIL
= 6x² + 7x - 3 ← in standard form
with a = 6, b = 7, c = - 3
Then
abc = 6 × 7 × (- 3) = - 126
