Which of the following methods would be the easiest to use to solve 2x2 + 4x – 3 = 0?
factoring
isolating the x2 term and finding the square root of both sides
using the quadratic formula
all three methods would be easy and effective

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°
