A ladder is placed against the side of a house. The top of the ladder is 12 ft above the ground. The base of the ladder is 5 ft away from the house. Find the length of the ladder.

a = 11 : 4

b = 38

c = 1 for every 6

-6 is the correct option from the above given options

i saw this question before, dont know the asnwer srry

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
