Question 40

A geometric diagram showing a circle with center O. A horizontal line AEB is tangent to the circle at point E. Points C and D are on the circle. Line segments EC, ED, and OD are drawn. A line segment CD is also drawn. There are single tick marks on segments CD and DE, indicating they are equal in length. The angle AEC is labeled as x degrees.

CCC, D D\,D and E E\,E are points on a circle, centre OOO. AEB AEB\,AEB is a tangent to the circle at EEE.

CD=DECD = DECD=DE Angle AEC=x∘AEC = x^\circAEC=x∘

Find the size of angle OEDOEDOED, in terms of xxx. Give reasons for each stage of your working.
