Answer:
130 degrees
Step-by-step explanation:
AED is an iscosceles triangle so angle ADE will also be 65 degrees.
Angles in a triangle add up to 180 degrees so 65 + 65 =130 degrees, 180-130= 50 degrees.
Angle BEC is also 50 degrees because AED AND BEC are vertically opposite.
Angles in a circle add up to 360 degrees. 50 + 50 = 100. 360 - 100 = 260. 260/2=130 degrees
