a= 30degrees, because from the image a and 30 are vertically opposite angles .And vertical opposite angles are equal

because c and 75 are angles on a straight line and angles on a straight line sum up to 180.

Therefore

b+a+90=180degrees. Because they are the interior angles of a triangle. But a=30.Therefore

Group like terms

Therefore b=60degrees
