Answer 2

Answer:

65

Step-by-step explanation:

We know that angle at the centre made by an arc is double the angle made by same arc at any other point of the circle

so DC arc making an angle B and O so

the angle at B =25

then automatically

angle at O will be 50

so the difference of those two

= 50-25=25

that means 25 =DBC

and angle BDE=90

so angle DEC= 180-90-25=65
