show how to get numerical values

PROBLEM 4(20%) In the phase diagram below, A and B are the two components, and A and B are two solid phases. The start and eadpoint of the X-axis represent pure A and pure B, respectively. - How many phases and which ones do you have in the points indicated by the blue and yellow circle? What are their composition and relative abundance? (provide numerical values) PROBLEM 4(20%) In the phase diagram below, A and B are the two components, and A and B are two solid phases.
