Let, the first (smaller) number = x
Larger number = 8x
Then, 8x - x = 70
7x = 70
x = 70/7
x = 10
& 8(10) = 80
In short, Your Numbers would be, 10 & 80
Hope this helps!

Answer:
9cm
Step-by-step explanation:
making perpendicular "A" from center "O"
we get,OA=4cm(half of 8cm)
Now,
In triangle POA,
h^2=p^2+b^2
5^2=4^2+b^2
25=16+b^2
9=b^2
b=3cm
PA=3cm
hence,length of chords=3+3=9cm
