Question

You found a treasure map, and it's said: staring at well walk 30 m north, 20 m 30° N of East, 15 m 18° south of west, and finally 10 m north. How far is the treasure map from the well?

Answer 1

$x=20\cdot\cos30°-15\cdot\cos18°=3.055\ (m)$

$y=30+20\cdot\sin30­°-15\cdot\sin18°+10=45.365\ (m)$

$L=\sqrt{3.055^2+45.365^2}\approx45.5\ (m)$ . Answer
