Answer:
<ABC = 17
Step-by-step explanation:
I'm going to make a guess. My guess is that you want the measure of angle B. I didn't see that the diagram asks that very question.
If you join <ADC, that angle is also 34 degrees. By the property of angles touching the circumference of a circle, the angle touching the circumference is 1/2 the central angle
1/2 34 = 17
