Question

In given figure if AB||CD, then angle EFD is equal to
​

Answer 1

Step-by-step explanation:

AB || CD ( GIVEN)

SO BC IS TRANSVERSAL

angle ABC= angle DCE( CORRESPONDING ANGLE)

FCE+CDE= 180( LINEAR pairs)

FCE= 180-70= 110

NOW IN TRIANGLE FCE

EFC= 180-(110+30)

EFC= 180-140

EFC= 40

SO EFD= 40°

Answer 2

Step-by-step explanation:

EFD = 40
