One of the vertices of triangle PQR is P (2,-4). The midpoint of segment PQ is M (3,-2). The midpoimt6of segment QR is N (6,3). Show that segment MN is parallel to segment PR and MN=1/2PR

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

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°
