**drwls**, Thursday, November 25, 2010 at 9:16amA parallelogram has two equal angles A and two equal angles B. The equal angles are diagonally across from one another.

A + B = 180 degrees. Thus

2x + 25 + 3x -5 = 180

5x = 160

x = 32

A = 89

B = 91.

It is almost a rectangle.

**Bosnian**, Thursday, November 25, 2010 at 9:20amThe angles of a parallelogram satisfy the identities:

A=C

B=D

A+B=180°

A+B+C+D=360°.

C=A=(2x+25)

D=B=(3x-5)

A+B=180°

2x+25+3x-5=180°

5x+20°=180°

5x=180°-20°

5x=160°

x=160°/5

x=32°

A=C=(2x+25°)=2*32°+25°=64°+25°=89°

B=D=(3x-5°)=3*32°-5°=96°-5°=91°

A=89°

B=91°

C=89°

D=91°

A+B=91°+89°=180°

A+B+C+D=89°+91°+89°+91°=360°
