We will use the Pythagorean theorem:
b² = 19² - 3² = 361 - 9 = 352
b = √352 = 18.76 ≈ 18.8
sin A = 3 / 19 = 0.15789
m ∠ A = sin ^(-1) 0.15789 = 9.08° ≈ 9.1°
m ∠ B = 90° - 9.1° = 80.9°
Answer:
A ) m∠ A = 9.1°,  m∠B = 80.9°,  b = 18.8

A train is moving at an average speed of 180 m/s. how long will it take to reach the station. Both stations are 80 km apart?
Alexxandr [17]

1 km = 1000 meters.

Find total meters: 80 km x 1000 meters per km = 80,000 meters.

Divide total meters by the given speed:

80,000 meters / 180 m/s = 444.44 seconds.

1 minute = 60 seconds

444.44. Seconds / 60 seconds per minute = 7.41 minutes = 7 minutes 24.42 seconds

Total time = 7 minutes 24.42 seconds

Round as needed.

Blaise Pascal (June 19, 1623 - August 19, 1662) was a great contributor to math, science, and philosophy, especially Christian philosophy. Interesting Blaise Pascal Facts: Pascal's early education in France was conducted at home by his father due to the prodigious talent and understanding he showed as a child. Did u mean pascal instead of pasical becaus ethere is no such thing. Hope I helped :)
