In the figure above, if a:b:c = 3:4:1, what is the value of a?
Darina [25.2K]

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

I hope this helps and please don't hesitate to ask if there is anything still unclear!
