need help w/ reason for m<BPC + 2(m<PBC) = 180

[JayJay06]

I need help with the reason for this statement. The statement is:

m<BPC + 2(m<PBC) = 180
m<APB + 2(m<PBA) = 180

Reason:

I think the answer is: Supplement Postulate.

Is that correct or incorrrect?

Thank you for the help.

Since we have no information regarding the points or angles or anything else, there is no way for us to know how they might be related, or if the statement is even reasonable. Sorry. Too bad your book didn't give a picture or any other explanation.
