Robert and Chris can skate 4 miles in 18 minutes. How far can they ride in 45 minutes?

5050 i think

step-by-step explanation:

its an acute right triangle

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°

not sure but it may be b, as i said i'm not sure.
