Ateacher is having three students take care of 28 goldfish during the summer. he gave some to alain. then he gave twice as many to miguel. he gave twice as many to kira as he gave to miguel. how many fish did each student get?

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°
