Part A$.$ Address Questions below dealing with solar angles and the sun's position $($show sketches always!$)$

Sketch earth $($ a circle $)$ and draw a horizontal line $($ equator $)$ and vertical line $($ axis of rotation $),$ Now show

solar rays coming horizontally from the left. This is the Equinox $($Sept $21).$ Mark the $30\mathrm{.}5$ degree latitude

$($CS$,$ TX$)$ where you are with a stick figure$--$you$--$standing on the earth's surface with a vector coming out

of your head. Check to see if the angle between this vector and horizontal solar rays are $30\mathrm{.}5--$your latitude.
