Which graphs have a line of symmetry? Check all of the boxes that apply. On a coordinate plane, a parabola opens to the right. On a coordinate plane, a function crosses the x-axis at (negative 3, 0), (negative 1.5, 0), (negative 0.5, 0), and (1, 0). On a coordinate plane, a cosine curve has a maximum of 1 and minimum of negative 1.

a is the right answer

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°
