The supplement of an angle measures 11 times its complement. Then the measure of the angle is:

(A) 9 degree
(B) 99 degree
(C) 81 degree
(D) 90 degree
(E) none of these

not just answer, please tell me how to do it

  • math -

    Supplement Angle=180-Angle
    Complement Angle=90-Angle

    As per condition
    Angle =180- 11(90-Angle)
    10 Angle =990-180
    Angle =810/10
    Angle =81 degree
