Which expression calculates the speed in meters per second of an object that travels a distance of 40 m every 10 s?

40⋅10

10 ÷ 40

40 ÷ 10

40 + 10

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°
