The time taken by an average swimmer to swim 100 meters, free style, at age x years is given by t(x) = 0.181x2 – 8.463x + 147.376 seconds. According to this model, which of the statements below is correct?

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°
