find measurement angle bac db and dc are paralell, da intersects bc, angle a is 65 degrees so i multipied by two and came up with the answer 130 degrees, is this correct? thanks

  • geometry -

    I cannot follow your description.
    Since DB and DC are parallel, D is on both lines, and
    BDC must be a straight line.
    So how does DA intersect BC ???
