Hey there!
In this picture, we have many pairs of adjacent angles:
1 and 2
2 and 4
4 and 3
3 and 1
This is because these pairs are being connected by a vertex and a side.
Hope it helps and have a great day!!!
Given,
Rate of free fall = 216 km/h
Solution,
km/h to m/s is converted as follows :

So, the rate of fall is 60 m/s.
If t = 20 s
Assume, initial velocity = 0
It will move under the action of gravity.
Using equation of motion,

Hence, this is all for the solution.
The height of the tank is 12 inches
(0.35x + 0.14 * 18) / y = 0.23
x + 18 = y
The lowest common denominator for 8 and 12 is 24. So you would need 3 packages of hotdogs and 2 packages of buns.
