Choose 1

(Choice A)
A
Replace one equation with itself where a quantity is added to only one side

(Choice B)
B
Replace one equation with itself where the same quantity is added to both sides

(Choice C)
C
Replace only the right-hand side of one equation with the sum/difference of the right-hand sides of both equations

(Choice D)
D
Replace one equation with the sum/difference of both equations

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

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°
