20/q = 7/9
20×9 = 7q
7q = 180
q = 180/7
The answer is B. Adjacent angles. They both have a meeting point and don't overlap.
The answer isn't A. because both angles don't add up to 90°.
The answer isn't C. because both angles aren't 90°.
The answer isn't D. because both angles don't add up to 180°.
Hope this helps! :)

Graph A because the slope and y intercept is correct on that graph
So what you need to do is find the volume and divide it by 2.
Explanation:
The common difference of this arithmetic sequence is 5. Adding 5 to an even number gives an odd number, and vice versa. Hence the "parity" of the terms in the sequence must alternate between odd and even.
