Step-by-step explanation:
step 1. x + 51 + 39 + 127 = 360 (1 revolution is 360°)
step 2. x + 90 + 127 = 360
step 3. x + 127 = 270. (subtract 90 on both sides)
step 4. x = 143° (subtract 127 on both sides)
The expression that represents the profit is: ( 5x2 + 2x – 80)-(<span>5x2 – x + 100)
Profit can be modeled by polynomial expression: 3x-180
