Answer:
Step-by-step explanation:
It is assumed the width of the street is the distance between the opposite buildings.
<em>See the picture attached</em>
<u>It comprises of two parts: </u>
<u>Using Pythagorean theorem, lets find the value of x:</u>
- x² + 15² = 17²
- x² = 289 - 225
- x² = 64
- x = 8 m
<u>Same rule for y:</u>
- y² + 8² = 17²
- y² = 289 - 64
- y² = 225
- y = 15 m
<u>The width of the street (road) is:</u>
1.<span> an environment or material in which something develops; a surrounding medium or structure.</span>
2. <span>a mold in which something, such as printing type or a phonograph record, is cast or shaped.</span>
