Galileo's telescope showed him that Venus has a large angular diameter (61 seconds of arc) when it is a crescent and a small angular diameter (10 seconds of arc) when it is nearly full. Use the small angle formula to find the ratio of its maximum distance to its minimum distance. HELP!!!!
 
Assume its size is fixed, to appear bigger or smaller it must be further away. Sketch two thin triangles (you can't draw seconds of arc.) A circle is 360 degrees, A minute of arc is 1/60 of a degree, A second of arc is 1/ 60 of a minute.

figure the ratio of the length of the long side if the angle is smaller.
