IN ANSWERING QUESTIONS 4-13 THROUGH 4-17,
REFER TO FIGURE 4-F,
LOCATED AT THE END OF
THIS ASSIGNMENT.
FIGURE 4-F PERTAINS TO A
CELESTIAL FIX OBTAINED BY THE INTERSECTION
OF THREE LINES OF POSITIONS.
FIGURE 4-F
SHOWS HOW (UNDER IDEAL CONDITIONS) A FIX
CAN BE OBTAINED DURING THE DAYTIME BY
OBSERVING THE SUN, MOON, AND VENUS.
THE
SIZE OF THE RESULTING TRIANGLE HAS BEEN
ENLARGED IN RELATION TO THE REST OF THE
DIAGRAM STRICTLY FOR ILLUSTRATIVE
PURPOSES.
