    Answer:

    155 degree

    Step-by-step explanation:

    let <A, <B,<C are three angles in a triangle.

    sum of the three angles in a triangle is 180degree.

    <A+<B+<C=180

    130+<B+<C=180 since one angle is given

    <B+<C =180-130

    <B+<C=50

    (<B+<C)/2=25—-(1)after bisecting sum of the angles

    required angle =180-25=155
