    Answer:

    Distance between starting point to end point = 171 ft

    Explanation:

    distance to be calculated is AB

    AB = AC + BC

    AC,  Cos 60

    = AC ÷ 135

    AC = 135 cos 60

    = 67.5 ft

    BC, Cos 40

    = BC ÷ 135

    BC = 135 cos 40

    = 103.416 ft

    AB = 67.5 + 103.416

    = 170.9159998210 ft

    Distance between starting point to end point = 171 ft
