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°
