Determine which relation is a function. O {(-4, 1), (-2, 3), (-1, 2), (3, 5), (3, 2)}
O {(4, 1), (-2, 3), (-1, 1), (-1, 5), (3, 2)}
O {(-4, 1), (-2, 3), (-2, 1), (-1, 5), (3, 2)}
O {(-4, 3), (-2, 3), (-1, 2), (2,5), (3, 2)}

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°
