Question

answer the following​

Answer 1

Answer:

Angle BEC = 68

Step-by-step explanation:

as bith the angles BAC and BEC are on the same base BC

Answer 2

Answer:

34°

Step-by-step explanation:

angle ACD is exterior angle of triangle ABC

hence,

angle ACD = angle ABC + angle BAC

angle ACD = angle ABC + 68°

dividing both side by 2 we have

angle ACD/2 = angle ABC/2 + 34° .............(1)

now, angle ACD/2 = angle ECD ..(EC is bisector)

angle ABC/2 = angle EBC...(EB is bisector)

putting the above values in (1) we have

angle ECD = angle EBC + 34°................(2)

now, angle ECD is exterior angle of triangle ECB

so,

angle ECD = angle EBC + angle BEC..........(3)

comparing (2) and (3) we have

angle BEC = 34°
