Now, we know that 90°< θ <180°, that simply means the angle θ is in the II quadrant, where sine is positive and cosine is negative.

Answer:
About 15%
Step-by-step explanation:
3 divided by 19 is 0.1578947368421053
0.1578947368421053 multiplied by 100 is 15.78947368421053.
We have the representation of this problem in the figure below. As we have a 10.3 mile race, then the equation is fulfilled as:

We know that there is <span>a water station that is twice as far from the starting line as from the finish line, then:
</span>

So:

∴

and

<span>Finally, the distance of the runner from the finish line is:
</span>
Answer:
Hey there!
We can use the midpoint formula to find that the midpoint is (-1, -9).
