Thread: The measure of an angle.

Ok, this has probably already been asked and solved; if so, please link me. Spent hours upon hours looking this up and I can't get anywhere.

In short, think of a clock; the hour hand is always at 12 and the second hand rotates around like normal.

What I know:
The radius of the circle and the length of the lines.

I need to know the formula for the angle measure where the hour hand and the second hand intersect?

Thanks in advance

Both hands point at the 12. Consider a period of 12 h. During this time the hour hand and the second hand (btw that's really a nice expression ) will meet

times = 719 times

That means after the hand meat again. Since 1 hour is related to 30° with the hour hand the angle is:



That's the angle the hour hand describes between two intersections.
