#1**+3 **

In the center, there are 6 angles. The sum of the measures of these 6 angles = 360º

Since each angle has the same measure, we can say 6 * measure of one of these angles = 360º

so...

the measure of one of these angles = 360º/6 = 60º

In the picture, I just added 60º to the measure every time I went another 60º.

So, when Q is rotated 240º clockwise, it will end up where U is now.
