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.

It was a small battery powered device that delivered nicotine liquid solution in a vaporized form, fog, when inhaled air activates an atomizer. It had a red light at the tip that lighted up with each drag. It did not contain the substances commonly found in regular cigarettes, such as, tar and other cancer causing agents. Hon Lik gave one of the first prototypes to his father, who was also a heavy tobacco smoke and dying of lung cancer at that time. His father enjoyed the electronic cigarette and was happy that with the device there would be fewer sons watching their fathers dying of lung cancers.
