    Answer:

    Step-by-step explanation:

    sum of for angles of a quadrilateral=360

    111+134+69+x=360

    314+x=360

    x=360-314=46

    fourth angle=46°

    All angles of a quadrilateral add up to 360 degrees, so 111+134+69+x=360

    Solving it we get:

    314+x=360
    x=46 degrees.

    I hope this helps!
