    Answer:

    Angle A=85 and Angle B=95

    Step-by-step explanation:

    Sum of adjacent angles of a parallogram is supplement

    So (4x-15)+(5x-30)=180

    X=25

    No substitute, 4x-15,5x-30

    4(25)-15=85

    5(25)-30=95

    And I hope this correct and Mark me as brainlest and rate

    Step-by-step explanation:

    Sum of two angles of one side is 180° in a parallelogram.

    A+B =180°

    4x-15 + 5x-3 =180°

    or, x= 22°

    opposite angles are equal

    A= 4×22 –15 =73° = C

    B=5×22–3=107°=D
