Q. A treasure map...

Soln.

1) distance = [(15-5)²+22²] = 24.2 m
Angle = tan¹(22/10) = 65.6°
Location 1 = 24.2 m from palm tree N 65.6° E

2) distance = [(15+5)²+22²] = 29.7 m
Angle = tan¹(22/20) = 47.73°
Location 2 = 29.7 m from palm tree N 47.73° E

3) Location 3 = 29.7 m from palm tree N 47.73° W

4) Location 4 = 24.2 m from palm tree N 65.6° W

So,
24.2 m ,65.6° E of N
29.7 m ,47.7° E of N
29.7 m ,47.7° W of N
24.2 m ,65.6° W of N
