two trains leave the station at the same time one is heading east and the other one is heading west the eastbound train travels at a rate of 45 miles per hour the westbound train travels at a rate of 55 miles per hour how long will it take for the two trains to be 280 miles apart

d? maybe

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°
