<p>I have two questions,

  1. If hiker walks on level ground 10 miles due north , 5 miles due east , and 2 miles due south , how far , in miles , is hiker from his starting point.
  2. In xy plane , Triangle PQR is located so that point Q has coordinate (0,3). side PR is parallel to the x axis and has length 4 .if sides PQ and QR are equal in length . Which of the following could be the x coordinate of point P ?
    A)-5
    B)-4
    C)-3
    D)-2
    E)-1
    please help me</p>

<ol>
<li><p>The hiker’s displacement is 8 miles north, 5 miles east from his starting point. By Pythagorean thm, the straight-line distance from his starting point is sqrt(8^2 + 5^2) = sqrt(89).</p></li>
<li><p>Draw a picture; PQR is isosceles and is symmetric about the line x = 0.The only possible x-coordinate of P (out of the answer choices) is D) -2.</p></li>
