a triangle,side ac is 3/5 of side ab,and is 23.1 m. side ab is 7/9 of side bc.angle b is 1.5 times larger than angle c,and angle a is twice the size of angle c.how many degrees is angle A

  • math -

    ignore all that noise about side lengths. Working with the angles,

    b = 3/2 c
    a = 2c

    a+b+c = 180
    2c + 3/2 c + c = 180
    9c = 360
    c = 40
    so,
    a = 80
    b = 60

    you can check on the side lengths of you wish, to make sure they obey the law of sines.
