    Answer:

    let x,y,z be the three angles of the triangle.

    x+y+z=180° – sum of all angles of a triangle.

    According to question:

    y=1/3x. -(1)

    and z=x+26.° -(2)

    from(1)

    x=3y and z=3y+26°

    therefore,y+3y+3y+26°=180°

    7y+26°=180

    7y=154°

    y=22°

    x=3y=66°

    z=3y+26°=66+26=92°

    hope it will help you and mark me as braniliest.
