First, you need to figure out how many people are paying. Since it is Hank and his two friends, three people will be paying. Next, you need to divide 129.00 by 3. 129/3=43. Each friend will pay exactly $43.00.
I don’t exactly know what you’re asking, but cotangent = cosine/sine or another way of writing it is sine = cosine/cotangent
Hope this helps!
Stay safe and have a great day :D
