Find B round to the nearest tenth!!!! laws of cosines!!!!

AlexFokin [52]

Answer:

32.7°

Step-by-step explanation:

Use the formula for law of cosines, for this question we need so solve for angle B, so use...

b² = a² + c² - 2(a)(c)Cos B

We are given a, b, and c, so plug them in...

55² = 90² + 50² - 2(90)(50)Cos B

Now simplify...

3,025 = 8100 + 2500 - (9000)Cos B

-7,575 = -(9000)Cos B (subtract 8100 and 2500 from both sides)

0.841666667 = Cos B (divide both sides by -9000)

Cos^(-1) 0.841666667 = B (use cosine inverse function on calculator)

Train A and train B leave the station at 2 pm. The graph below shows the distance covered by the two trains. Compare the two spe

jarptica [38.1K]

Both trains travel for 7 time units.

Train A travels 385 distance units, so its speed is

$\dfrac{385}{7}=55$

Train B travels 577.5 distance units, so its speed is

$\dfrac{577.5}{7}=82.5$

Note that the units are not specified, but considering that we're talking about trains, the graph is likely to be showing distance in km (or miles) and time in hours.

Also, the distance traveled by train B is not perfectly aligned with the grid, so I assumed that it was the average between the two ticks of 550 and 605.
