I just started intoductory astronomy and I have difficulty understanding this problem. Any help would be appreciated

 

For a place at a latitude of 55 degrees, determine how high above the horizon the sun is at noon on

 

1) The Vernal Equinox

2) The summer solstice

3) Winter solstice

What latitude are the equator, the tropic of Cancer and the tropic of Capricorn?

 

Why have I asked you these three questions?

 

That should give you enough hints?

It helps to draw a 2-dimensional picture (from the side obviously). Or play with a 3D version, using a lamp, and something spherical with the equator and earth's axis painted on it, and at the right angles.
