Find the shortest distance from A to B in the diagram below. A. 505‾‾‾‾√ m B. 17 m C. 329‾‾‾√ m D. 10 m
marin [14]

The shortest distance from A to B in the diagram is 17 m.

<h3>How to find the shortest distance?</h3>

The shortest distance from D to B can be found as follows:

using Pythagoras theorem,

c² = a² + b²

where

  • c is the hypotenuse
  • a and b are the other legs

Therefore,

DB² = 15² + 8²

DB² = 225 + 64

DB² = 289

DB = √289

DB = 17 m
