First notice that the vertical ditches are parallel to each other Therefore the distance between them is constant and equal to 475 meters Now lets consider the right triangle formed by the horizontal ditch the vertical ditch on the left and the diagonal line connecting them We can use the Pythagorean theorem to find the length of the diagonal line a2 b2 c2 where a 305 meters b unknown and c 320 meters Solving for b we get b sqrtc2 a2 sqrt320 m2 305 m2 132 m Therefore the distance between the ...View the full answer
