TIP

Close obserservation the circle is divivded into 4 quadrants

STEP

each quadrants is 90

first 2 is 90 in the first quadrant

second 2 is in the third quardrant

STEP

Third quadrant 3+1+2=6

90/6=15each

second 2 in the third quadrant 2times 15=30

Third 2 is in the fourth quadrants

STEP

fourth quadrants 1+2+1=4

90/4=22.5

third 2 in the fourth quadrants

2 times 22.5=45

90+30+45=165

total sum of angle is 360

$\begin{gathered} (165)/(360)*120 \\ =55\text{ times} \end{gathered}$
