How to work out those annoying angle problems Let's look at another problem, similar to the one gone over in the previous section dealing with how to use the declination values of objects. All problems like these have 3 parts - • A latitude • The declination of an object (how far it is from the Celestial Equator) • The height above the northern or southern horizon The diagram that helps you figure out the problem, like that shown in Figure 8, shows only the northern and southern horizon. Why not the eastern or western horizon? You might want to think of these problems as meridian problems, since that is where we are looking at the objects in the sky, when they are on your meridian (I hope you didn't forget what the meridian is, because if you did, you may want to look it up again). Anyways, the diagram just shows the angles along the meridian going from the ground, the horizon, and extending upwards. You really need to get your brain around these problems, since they will definitely be on the test. Let's go back to the set up in Figure 8, the way that the sky is oriented along your meridian as
