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:
Step-by-step explanation:
using sine formula
let ∠ADB=y
then ∠CDB=180-y
∠DAB =180-(35+y)

Step-by-step explanation:
a. 3 1/7 b. 3 1/6 and c. 2
Ok, I'm not giving you the answer. Instead, I'm going to give you the way to solve it. Then, you can do it yourself, message it to me, and I will check it.
