Answer:
8 ft
Step-by-step explanation:
Okay lets get our variables and notes down first, I'll use the most common terms for this.
Hypotenuse: 12 ft <-- The ladder is the hypotenuse
Leg: 9 <- The height of the top of the ladder on the house
Base: ? <- We need to solve for it.
Pythagorean Theorem says c²-a²=b²
c = Hypotenuse
a & b are both Legs and interchangeable
12²-9²=b²
144-81=b²
63=b²
=
=b which is approximately 7.93 which rounds up to 8

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
