Answer:
12 meters
Step-by-step explanation:
Given That :
Length of ladder = 15m
Height of wall =. 9 m
Using Pythagoras rule :
Adjacent² = hypotenus² - opposite²
Adjacent² = 15² - 9²
Adjacent² = 225 - 81
Adjacent² = 144
Adjacent = sqrt(144)
Adjacent, x = 12
Use Euler's formula for polyhedra: V - E + F = 2
vertices - edges + faces = 2
So edges = vertices + faces - 2 = 18 + 11 - 2 = 27.
Answer:
27 edges.
