in a paralleogram,if angle A=(2x+25)degree and angle B=(3x5)degree,find the value of x and the measure of each angle of the parallelogram.

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=(3x5)
A+B=180°
2x+25+3x5=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=(3x5°)=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° 
find the of each parallelogram and what lathr mean like u' f.v.y.n
