Like poles repel, unlike attract. The term North pole, or South pole, is a very misleading and confusing term, to be avoided. Check your text on that. Most use the term N-pole, or S-pole, which means North seeking pole, or South seeking pole. Those are much more meaningful terms.

Lindsay is out one night and notices that her body casts a shadow that is 1.8m long when she is standing 5mfrom the pole supporting a street light Lindsay is 1.5m tall. 1-what is the angle of elevation to the street light ? 2- how high is the street light
