in a paralleogram,if angle A=(2x+25)degree and angle B=(3x-5)degree,find the value of x and the measure of each angle of the parallelogram.

• math -

A 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.

The 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°
