Answer:
30
Step-by-step explanation:
The line is divided up into 3 parts, a part of 3, a part of 4, and a part of 1. If we had those parts together we get 8 meaning if we divided the line into equal parts that also fit into a, b, and c there would be 8. We can than divide the line into 8 parts which would be 10 each since a line is 180 degrees. Since a is 3 than a gets 3 of those parts meaning a would be 30
