An 84-square foot tabletop is starting to bow in the middle. Using only the scrap wood in her shop, a carpenter adds a diagonal support piece to the square shaped tabletop. Which of the following lengths of scrap wood is
closest to the length the diagonal support piece?

sine

step-by-step explanation:

7,24

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°
