Answer:
B
Step-by-step explanation:
The sum of the angles of the triangle add up to 180 degrees.
x and y are equal to each other in this type of the triangle.
This is an arith. sequence, and the common difference is -9.
a(n+1) = a(n)-9, with a(1)=8. Thus, if we look at the first term, we see 8; subracting 9 from 8 produces the second term (-1).
