Marguerite drew a rectangle with vertices a(-2,-1) b(-2,-4) and c (1,-4) what are the coordinates of the fourth vortex?

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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°
