In Part A you chose an expression for the pattern that the numbers continue in. Part B is asking you to use that expression to find the 20th number in the pattern. 

If the expression is 4n+4 and n represents the #th number then this is how you would solve the expression:

4(20)+4

80+4 = 84

So, the answer to Part B is 84.

The 20th expression would be 80. Counted on my fingers xD hit 80 when i did 20 fingers. which means that if you put 20 as n, it should come out to 80, but it comes out to 84 by the answer you chose, so I'm wondering if the answer you chose was right, or if it was A

After a storm, a tree lies as shown. What was the original height of the tree? (Round to the nearest whole foot.)
Andreyy89
Using the Law of Sines, sina/A=sinb/B=sinc/C (although there are other ways considering that this is a 30, 60, 90 degree triangle with a basic identity) we can say:

97/sin60=x/sin30=y/sin90

x=97sin30/sin60 and y=97sin90/sin60

The total height of the tree is h=x+y so

h=97sin30/sin60 + 97sin90/sin60

h≈168.01 ft (to the nearest hundredth of a foot)

h≈168 ft (to nearest foot)
