    35° and 55°

    Step-by-step explanation:

    The sum of the angles of a right rectagle is 180°, with a right angle of 90°.

    The tell us that A = 2B-15, so:

    180° = 90° + A + B

    180° = 90° + 2B - 15 + B

    180° - 90° + 15 = 2B + B

    105° = 3B

    B = 105°/3 = 35°

    Now, let's find A:

    A = 180° - 90° - 35° = 55°
