X+y=90 Degrees

12/16 Math League News
Since their sum is 180 degrees, x + y = 90 degrees. Therefore, in right triangle BKO, angle KBO is y, so cos y = 1/ r. In triangle BOC, use the law of cosines to get 12 2 = 2 r– 2 cos y. Substituting 1/ r for cos y and simplifying, 72 = ( r)( r – 1), so r = 9. ... Doc Retrieval
