Answer:
The first option.... The one with the blue dot I guess you have chosen that
The function is defined only if
. So, the leftmost point is
, and we have

So, the first point is 
The three additional points seem arbitrary, so let's choose
. We have:

So, the second point is 

So, the third point is 

So, the fourth point is

Answer:
A ≈ 65.4°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the trig relations associated with pairs of sides. For angle A, given sides b and c are the adjacent side and the hypotenuse, respectively. The appropriate relation is ...
Cos = Adjacent/Hypotenuse
cos(A) = b/c
A = arccos(b/c) = arccos(2.5/6)
A ≈ 65.4°
