Question 1. Find the 9th term for the sequence a(n)=7-9n Question 2. Find a function that describes the arithmetic sequence 16, 17, 18, 19, ... Use y to identify each term in the sequence and n to identify each term’s position.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

i think it would be c
