Members of a club are making friendship bracelets to sell. Kate and Brooke made 126 bracelets over the weekend. They need to produce 315 bracelets by the end of the week. What percent of the total number of bracelets did they already produce? *

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°
