To find the measure of angle CAB, you can use the angle sum property of triangles. The sum of the angles in any triangle is always 180 degrees.
In this case, we know the measure of angle DAB is 50 degrees and the measure of angle DAC is 20 degrees. We need to find the measure of angle CAB.
Since angle DAB and angle DAC are adjacent angles that share side DA, we can subtract their measures from 180 degrees to find the measure of angle CAB.
180 degrees - 50 degrees - 20 degrees = 110 degrees
Therefore, the measure of angle CAB is 110 degrees.
