Answer: option d
Step-by-step explanation:
Remember the identity:

The inverse of the tangent function is arctangent. You need to use this to calculate the angle "S":
Knowing that: you need to find the measure of the angle "S" ,
(which is the adjacent side) and
(which is the opposite side), you can sustitute values into 
Then, you get that the measure of "S" rounded to the nearest tenth is:

Answer:
they are parallel to each other is the best choice to describe the bases of a cylinder. The answer is PARALLEL
Given:

To find:
The number of possible solutions, if the Order of Operations did not exist.
Solution:
We have,

Now,
Case 1:
![[4 + 9 + 16] \div [4 - 8 -(3 \times 5)]=29\div (4 - 8 -15)](https://tex.z-dn.net/?f=%5B4%20%2B%209%20%2B%2016%5D%20%5Cdiv%20%5B4%20-%208%20-%283%20%5Ctimes%20%205%29%5D%3D29%5Cdiv%20%284%20-%208%20-15%29)

Case 2:
![[4 + 9 + 16] \div (4 - 8 -3) \times 5=29\div (-7\times 5)](https://tex.z-dn.net/?f=%5B4%20%2B%209%20%2B%2016%5D%20%5Cdiv%20%20%284%20-%208%20-3%29%20%5Ctimes%20%205%3D29%5Cdiv%20%20%28-7%5Ctimes%205%29)

Case 3:


Many more possibilities are there.
Therefore, there are more than 3 possible solutions.
