Answer:
a. Library card
Step-by-step explanation:
A bank is most comfortable with a government-issued picture ID. A library card usually will not provide any assurance that you are who you say you are.

Base Dimension


Required
The base area of all containers
First, calculate the base area of 1 container.
This is calculated as:


Express as improper fraction

So, we have:


The number of containers is not given. So, I will use 'n' as the number of containers.
So, we have:


--------------------------------------------------------------------------------------------
Assume n is 3 (i.e. 3 containers)
The total area is:

Answer:
A ≈ 119.7°, b ≈ 25.7, C ≈ 24.3°
Step-by-step explanation:
A suitable app or calculator does this easily. (Since you're asking here, you're obviously not unwilling to use technology to help.)
_____
Given two sides and the included angle, the Law of Cosines can help you find the third side.
... b² = a² + c² - 2ac·cos(B)
... b² = 38² + 18² -2·38·18·cos(36°) ≈ 661.26475
... b ≈ 25.715
Then the Law of Sines can help you find the other angles. It can work well to find the smaller angle first (the one opposite the shortest side). That way, you can tell if the larger angle is obtuse or acute.
... sin(C)/c = sin(B)/b
... C = arcsin(c/b·sin(B)) ≈ 24.29515°
This angle and angle B add to less than 90°, so the remaining angle is obtuse. (∠A can also be found as 180° - ∠B - ∠C.)
... A = arcsin(a/b·sin(B)) ≈ 119.70485°
