Question

in the adjoining figure lines AB and CD intersect at F. if ZEFA=ZAFD and ZCFB=50°,find ZEFC​

Answer 1

Answer:

answer to the above question is given in the attachment

Answer 2

Answer:

<EFC = 80 Degree.

Step-by-step explanation:

<CFB = 50 degree

<CFB = <AFD [Vertically Opposite angles]

<AFD = 50 degree

<EFA = <AFD [Given]

<EFD = 50 degree

We know that,

<EFA + <EFC + <CFB = 180 degree [ Straight Angle]

50 + <EFC + 50 = 180 degree

100 + <EFC = 180 degree

<EFC = 180 - 100

<EFC = 80 Degree.

There you go!
