Answer 1

Step-by-step explanation:

Interior angles on the same side of the transversal are supplementary.

∠A+∠B=180o∠A+∠B=180o

⇒(3x+2)o+(2x−32)o=180o⇒(3x+2)o+(2x−32)o=180o

⇒3x+2+2x−32=180o⇒3x+2+2x−32=180o

⇒5x−30=180o⇒5x−30=180o

⇒5x=210⇒5x=210

⇒x=42o⇒x=42o

Thus, ∠A=3x+2=3×42o+2=128o∠A=3x+2=3×42o+2=128o

∠B=2x−32=2×42o−32=52o∠B=2x−32=2×42o−32=52o

Also, opposite angles of a parallelogram are congruent.

∠A=∠C=128o∠A=∠C=128o

∠B=∠D=52o∠B=∠D=52o
