What order will result in a final output of 2 when the first input is 8? (See screenshot)

The order that will result in a final output of 2 when the first input is 8 is as follows;

Third → Second → Fourth → First

Step-by-step explanation:

First gives;

y = -2·x + 34 = 18

Second gives;

y = -x/3 - 10 = -38/3

Third gives;

= -24

Fourth gives;

y = (x - 2)² = 36

We have after several iterations;

Third gives;

= -24

Next we input into the second to get;

y = -(-24)/3 - 10 = 24/3 - 10 = 8 - 10 = -2

Next we input into the fourth to get;

y = ((-2) - 2)² =  (-4)² = 16

Next we input into the first to get;

y = -2×16 + 34 = -32 + 34 = 2

Which gives the order as follows;

Third → Second → Fourth → First

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
