Answer:
14
Step-by-step explanation:
the sum of the terms in the angle is 6x+6. Since the angles ate complementary their sum is 90 so you set the aforementioned sum equal to 90. You then solve for x and get 14.
-4/3 I believe is your answer.
The general form of the geometric sequence is

, where a sub n is the number term you're looking for (we're looking for the tenth term). a sub 1 is the first term in the sequence (ours is -6), r is the common ratio, and n-1 is the numbered term you're looking for minus 1. Our formula then looks like this:

. Simplify it to

. Take 2 to the 9th power then multiply it by -6 to get -3072. C is your answer.
