X=r-s/t
1.(S+tx)+(-s)=r+(-s)
2.s+tx-s=r-s
3.s-s+tx=r-s
4.tx=r-s
5.tx/t=r-s/t
6. x=r-s/t
Your answer is option D. √(15² + 19²). This is because the line PQ is the hypotenuse of this right triangle, so you can use the formula a² + b² = c² to find its length, which means it would equal the square root of 15² + 19², which is what option D expresses.
