Question

What is the measure of e then the angle of <efb​

Answer 1

Answer: angle EFB = 35 degrees

========================================================

Step-by-step explanation:

To get angle EFC, we will average the two arc measures given

This means we add them up and divide by 2

angle EFC = (arcEC + arcBD)/2

angle EFC = (164+126)/2

angle EFC = 290/2

angle EFC = 145

Then we can say:

(angle EFB)+(angle EFC) = 180 ... the two angles are supplementary

(angle EFB) + (145) = 180

angle EFB = 180-145

angle EFB = 35
