In ΔXYZ, x = 5.6 inches, y = 9 inches and ∠Z=68°. Find the area of ΔXYZ, to the nearest 10th of a square inch.

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°
