Question

EXAMPLE 4 A ladder is placed in such a way that its foot is at a distance of 5 m from a wall and its
tip reaches a window 12 m above the ground. Determine the length of the ladder.​

Answer 1

Step-by-step explanation:

length of the ladder is the hypotenuse of the triangle formed

let the height of the ladder be x m

therefore

5²+12²=x²

25+144=x²

x²=169

x=√169

=13m

the height of the ladder is 13m

Answer 2

Answer:

height =12m (let say A)

base= 5 m (let say B)

lenght= ? (let say C)

by phthgorous

C^2=A^2+B^2

C^2= 12^2+5^2

C^2=144+25

C^2=169

C=13m

Hence ,the length is 13 m
