Aboat traveled north for 28 miles, then tuned x° southwest and traveled for 25 miles before stopping. when it stopped, the boat was 18 miles from its starting point. rounded to the nearest degree, the boat turned degrees when it made its first turn.

The boat turned 46° when it made its first turn

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

I have made an illustration to better help you understand the situation and have attached it as a photo below. As you can see the problem forms a triangle and we need to find the value of the angle x . We can use the Law of Cosine to solve for the value of x.

Now we plug in the values given and solve for x

.... subtract 1409 on both sides

.... divide by 1400 on both sides

.... use cos on both sides

Finally, we can see that the boat turned 39.19° when it made its first turn

I hope this answered your question. If you have any more questions feel free to ask away at .
