Question

12. In the adjoining figure, E is a point in the interior of Z AOB,
such that EC I OB and ED I OA. If Z AOB = 36°, what is the
measure of Z CED?
0x36°
CB​

Answer 1

Step-by-step explanation:

measure of angle CED is 144°

Step-by-step explanation:

first sum up all the angles of the quadrilateral.

90+90+36=216

subtract 216 from 360...because the sum of all angles of any quadrilateral is 360

therefore 360-216=144

Therefore measure of angle CED is 144.
