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:
x? + 152 = 172
x2 = 289 - 225
x? = 64
• x = 8 m
Same rule for y:
y? + 8? = 172 y² = 289 64
-
y = 225
y = 15 m
The width of the street (road) is:
8 m + 15 m = 23 m
