1.6395 is what I got hope this helps
D because there’s a pattern. Pattern for x is that it’s adding by one. Pattern for y is that it’s adding by 15
6 and 9/24 + 9 and 4/24 is the number you have to change it to to get your answer. After that, you add, and get 15 and 13/24.
Given:
A diagram of a circle O, 
.
To find:
The measure of arc DC.
Solution:
According to the angle of intersecting chords theorem:
Angle at intersection of chords = Half of the sum of intercepted arcs.
Let 
be the angle between the intersection of chords AC and BD.
(Linear pair)
Using the angle of intersecting chords theorem, we get
On simplification, we get
Divide both sides by 2.
Now,
Therefore, the correct option is C.
Since you don't have the picture, I can explain how to do the problem. Then, you can select the correct answer.
To find the area of a parallelogram, you must multiply the base times the height. If you have those 2 values, just multiply them and you will be done.
