Answer:
29.5 hours
Step-by-step explanation:
Amityville to Denton is 1625 miles.
Since we know that Sarah drives at 55 mph we can divide 1625/55 and get 29.45454... and I assume that they want it rounded so it will be around 29.5 hours
Step-by-step explanation:
Solution,
In above figure,
a+a+76°=180° (being straight angles)
2a+76°=180°
2a=180°-76°
2a=104°
a=104°/2
a=52°
Hence, I will use option c. 2a+76°=180° for calculation.
