    Answer:

    7.7 km 26°

    Explanation:

    The total x component is:

    x = 2.5 cos(35°) + 5.2 cos(22°) = 6.87

    The total y component is:

    y = 2.5 sin(35°) + 5.2 sin(22°) = 3.38

    The magnitude is:

    d = √(x² + y²)

    d = 7.7 km

    The direction is:

    θ = atan(y/x)

    θ = 26°
