Answer
0.75 or 3/4 is the answer (degree)
I just solved for the angles and use a graphing calculator to find the din and cosine values and multiply them
First, make 6 1/3 a improper fraction:

. Now we have 19/3*7/3:

.
Answer:
Parallel lines
Step-by-step explanation:
Line BC:

Line AD:

Adding both equations, in this case, gives us the point at which the lines intersect:

Since zero will never equal fourteen, the equation above means that lines BC and AD will never intersect. When two lines have no point in common, they are said to be parallel lines.
1/9-22/9-5/9
-21/9-5/9
-26/9
The answer is 5.50$ you have to divide 16.50/ 3
