What is the measure (in degrees) of the smallest interior angle of a triangle in which the exterior angle measures have the ratio 2:3:4?

The EXTERIOR angles   sum to 360 degrees    so they are 80  120   and 160 degrees

 

The EXTERIOR + corresponding INTERIOR  angle   sum to 180 degrees    so the smallest INTERIOR would be   180 -160 = 20 degrees
