18. ∆PQR =~ ∆RPA ( by SAS )
19. ∆DQR =~ ∆PQR ( by AAS )
20. ∆ARO =~ ∆PQO ( by AAS )
The answer should be about 7.3%. You can divide 147000 by 137000 to get about 1.0729. Subtract the one (as it represents 100%) and then convert the decimal into a percent. So 0.0729 would convert to 7.29%, but typically this would be rounded up to 7.3%. If it does not say to round up then don't.

Answer:</h3>
7.8%
<h3>
Step-by-step explanation:</h3>
In 5 days' time, the amount remaining is 0.6^5 = 0.07776 times the original amount. Since both people start with the same amount the amount remaining in Noelle's body will be this fraction of that in Karey's body after 5 days have passed.
0.07776 ≈ 7.8%
So for question 7 part A the picture will be a triangle similar to the the one that shows the umbrella's height. But the base will be 40 and the height will be 130.
for part B the angle of depression can be found using the trigonometric function of tangent.
tan x = 40/130
tan^-1 (tan x) = tan^-1 (40/30)
x = 17 degrees
I hope i am right
