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

• 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

thank you
