Answer:
Beta is 60 degrees, and the angle of A should be 30 degrees.
Step-by-step explanation:
Its a right triangle, so it equals 180 degrees, there's a perpendicular angle at 'C' so its 90 degrees, B and its angle of 'Beta' 60 degrees, and angle 'A' can be 30 degrees. if in need of more explanation please look into complimentary and supplementary angles should give you a good idea.
The last one. In arithmetic sequence, the difference between the terms is constant, in this case, the difference is 3
