8. D: The <em>longest sides of the quadrilaterals are 30 and 10</em>. That is a 30 : 10 ratio, which simplifies to <em>3 : 1, or </em>3/1. It's not 1 : 3 because it is the ratio between the large (comes first) to the small (comes second) figure.
9. B: <em>x corresponds to 26</em>, and from the previous problem, we figured out that <em>the sides of the larger figure are 3 times larger than the corresponding one on the smaller one</em>. So <em>x is 1/3 the length of 26</em>, which is 26/3.

Answer:
8.1
Step-by-step explanation:
1) Find the measurement of the angle of the arc:
let x = the missing angle
360 = 73 + 65 + 150 + x
x = 72
2) Find the circumference
r = 6.48
C = 2(6.48)(3.14)
C = 40.6944
3) Multiply the circumference by the angle measurement divided by the the angle measurement of the circle:
40.6944 * (72/360)
= 40.6944 * (1/5)
=8.13888
4) Round to the nearest tenth
