I have no idea how to solve this

mAB

= 2/(2+3+4) * 360 deg

= 80 deg

mBC

= 3/2 * mAB

= 120 deg

mCA

= 4/3 * mBC

= 160 deg

idek how to solve m angle A,B,C from just these informations..... sry......

Oh thanks! I'm pretty sure the angles are half the arc measure. So, A would be 60, B would be 80, and C is 40 :)
