Name an angle complementary to Complementary angles add up to 90 degrees. COA is supplementary to AOE (they add up to 180) AOB is 90 degrees AOD is 180 degrees COB is complementary to COD. And because COD is congruent to AOE (because vertical angles are congruent), COB is also complementary to AOE. So our answer is COB.
Mad Libs was invented in 1953 by Leonard Stern and Roger Price. Stern and Price co-created the game, but couldn't agree on a name for their invention. No name was chosen until five years later (1958), when Stern and Price were eating eggs Benedict at a restaurant in New York City.
The duo released the first Mad Libs book themselves in 1958. The first Mad Libs resembled the earlier games of Consequences and Exquisite Corpse. Stern and Price next partnered with Larry Sloan, a high school friend who was working as a publicist at the time, to continue publishing Mad Libs.he duo released the first Mad Libs book themselves in 1958.
