The intersecting chords theorem states that whenever two chords intersect, the product of their pieces is constant.
So, in this case, we have
Plugging your values, we have
This equation has solutions 
, but we can't choose 
, because it would lead to
So, the only feasible solutions is 
Answer:
8
Step-by-step explanation:
Hello,
This is related to ratios and proportions. We have a 12 foot tree that casts a 6 foot shadow, so now we are trying to figure out how tall is a tree that casts a 4 foot shadow.
We can set an easier method to get this.
12 = 6 (this means the 12 foot tree casts a 6 foot shadow)
x = 4 (this means how tall is the tree to cast a 4 foot shadow, the unknown height of the tree is denoted as x)
Then, we can cross multiply.
48 = 6x
Solve for x, which is the unknown height we are trying to figure out.
x = 8
He saved 30.25 last month. 169 - 48 = 121 divided by 4 = 30.25
