The two in the middle. B and C, I guess.
it the tenths I think.....
Answer:
8![\sqrt{13}](https://tex.z-dn.net/?f=%5Csqrt%7B13%7D)
Step-by-step explanation:
Using the pythagorean theorem (Assuming the house's walls are perpindicular to the ground):
a^2+b^2=c^2
we can find that 3=a and 29=c
3^2+b^2=29^2
9+b^2=841
b^2=832
b=![\sqrt{832}](https://tex.z-dn.net/?f=%5Csqrt%7B832%7D)
b=![\sqrt{64*13}](https://tex.z-dn.net/?f=%5Csqrt%7B64%2A13%7D)
b=8![\sqrt{13}](https://tex.z-dn.net/?f=%5Csqrt%7B13%7D)
That is the height that the ladder will reach

total units of ration = 4 +7=11
so, ratio would be (4*33)/11 : (7*33)/11
12 : 21 is the answer.
