The ratio of Nathan's nickels to dimes to quarters is 4 : 4 : 17.
<h3>What is the ratio ?</h3>
Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained within other value(s).
- Number of dimes = 1/5 x 40 = 8
- Number of nickels = 1/5 x 40 = 8
- Number of quarters = 40 - 8 - 8 = 34
The ratio = 8 : 8 : 34 = 4 : 4 : 17

Answer:
X=16
Step-by-step explanation:
8. Since A F is perpendicular to J K, you know angles J A F and K A F are congruent (both are right angles). Since A F bisects J K, you know the lengths of J A and K A are the same. Side A F is incident to both triangles, and of course the lengths A F = A F. So we have two side-angle-side triangles, and by the SAS postulate we have triangles J F K and K F A congruent to one another.
9. Yes. The corresponding sides in both triangles have the same lengths. (S K to K F; S J to F J; J K to itself) The claim then follows from the SSS postulate.
