Answer:
AB = 90 degrees
AC = 60 degrees
Step-by-step explanation:
Since every triangles angles equal to 180 you first subtract 30 from 180 which is 150 degrees. You can see there is a square around a vertex which means that angle is 90 degrees. Now subtract 90 from 150 which is 60 degrees. So the last angle is 60 degrees.
