We will solve using the law of sines as follows:

Now, we solve for X:
![\Rightarrow X=\frac{\sin(60)}{\sin(30)}\Rightarrow X=\sqrt[]{3}](https://tex.z-dn.net/?f=%5CRightarrow%20X%3D%5Cfrac%7B%5Csin%2860%29%7D%7B%5Csin%2830%29%7D%5CRightarrow%20X%3D%5Csqrt%5B%5D%7B3%7D)
So, the length of X is sqrt(3).
True, because it is reflected across the y=x line
It is not . There are multiple x values for the y values.
Distance from finish line can be computed by subtracting the amount he has ran from 3. Every minute he runs .5km, and we can use this to create a function to describe this instance.

The distance remaining is equivalent to the minutes multiplied by .5km for each minute subtracted from 3 which is the total distance.
It’s A I had this question before
