Let the measure of an angle be 'x'
Then the reflex angle will be measured by the formula (360-x)
x +(360-x) = 360
Answer:
Angle DAC is an exterior angle (because it son the exterior of the triangle) and idk the choices for the measure of Angle DAC are.... but i know that X is equal to 119 beacse that line its on makes a 180 degree line with 61. so 180-61 is equal to 119
