24. Find two numbers that each have exactly 16 factors
two of which are 8 and 12.
​

To solve the question, we draw a circle representing a great-circle section of the earth, with satellite at a point S above earth. Draw tangents from S to he circle, and from points A and B, to the center C.
Hence:
AC and BC are radii, and
SA⊥AC and SB⊥BC
∠ASB=154°
making the angular measure of the intercepted arc:
∠ACB=180-154=26°

26°
