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
