Given that angle CFE = angle CFA, m angle AFB = 23degrees and m angle EFD= 69 find m angle EFB https://media.edgenuity.com/evresources/2089405_9a2a45fc-318d-4db4-a810-2bc173965e7d.png
A.
139 degrees
B.
147 degrees
C.
155 degrees
D.
157 degrees

Answer 1

so given that angle CFE = angle CFA and from this diagramm you see that has 90 degree
given again that m angle AFB = 23 degrees and that m angle EFD = 69 degree

find m angle EFB = ?

m angle CFA = 90 degrees
m angle AFB = 23 degrees

m angle CFA = m angle AFB + m angle BFC

90 = 23 + m angle BFC

m angle BFC = 90 -23

m angle BFC = 67 degrees

m angle EFB = m angle BFC + m angle EFC

m angle EFB = 67 + 90

m angle EFB = 157 degrees so choice D. is right

hope helped
