Answer:
The ranger will need to clear trail for more than 10 2/3 additional hours.
Step-by-step explanation:
1. 180° ∑triangle angles=180°
2. 2x
3. 52°
128°
x + 154° + 78° = 360° {being complete turn}
x + 232° = 360°
x = 360° - 232°
x = 128°
(3 + 2i) - (5 - 7i)
Distribute the - sign
3 + 2i - 5 + 7i
Combine like terms
-2 + 9i
