make sure your calculator is in Degree mode.
Given that the 3 arcs are congruent, it means they have the same angle.
A circle measures 360 degrees, thus, let us divide it into three parts to get the arc length of the 3 arcs RC, CS, and SM which is in Circle A.
360 degrees / 3 = 120 degrees
Again, the three arcs are congruent so the length of arc RC is 120 degrees, same with arcs CS and SM.
They should subtract $ -20 because they went behind on how much they planned to save. Now this question can be tricky because some might say they lost 0 because they already had an extra $20 but it is only asking for the month of February and is only asking for each month not the entire year.
