[100 points] george and carmen went on a bicycle trip. they took a bus to their starting point, and then biked the rest. they traveled 300 kilometers in total and they biked 70 kilometers more thands they were bussed. let x= kilometers traveled by bike and y= kilometers traveled by bus. findo how many kilometers they traveled by bike

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°
