Answer:

  • 23 m

Step-by-step explanation:

It is assumed the width of the street is the distance between the opposite buildings.

See the picture attached

It comprises of two parts:

  • x and y

Using Pythagorean theorem, lets find the value of x:

  • x² + 15² = 17²
  • x² = 289 - 225
  • x² = 64
  • x = 8 m

Same rule for y:

  • y² + 8² = 17²
  • y² = 289 - 64
  • y² = 225
  • y = 15 m

The width of the street (road) is:

  • 8 m + 15 m = 23 m
