Question

1. An orange is peeled . 18 identical sectors are found . What angle do does each semicircular surface make with another in a whole Orange.

2. There are two points on the globe , A ( 20°S,35°W) and B(20°S, 15°E). What is the longitudinal difference between the two points.​

Answer 1

#1

Since the circle covers 360°, each sector will be:

• 360°/18 = 20°

The same angle will be made between two adjacent semicircles.

#2

The points have same latitude but different longitude.

35°W and 15° are at different sides from zero longitude.

The difference is:

• 35° + 15° = 50°
