Mary needs to row her boat across a 200m wide river that is flowing to the east at a speed of 1.4m/s . mary can row with a speed of 2.2m/s what is her speed with respect to the shore?

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

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°
