Question

AB parallel CD parallel EF​ find x ​

Answer 1

Answer:

LET X=1 SO EF×1= EFX¹ SO IT WILL BE X¹FE

Answer 2

Answer:

so simple

Step-by-step explanation:

since EF is parallel to CD

angle FEC + angle ECD = 180°

co interior angles

130° + ECD= 180°

ECD = 180 - 130

= 50°

since AB parallel to CD

angle ABC = angle BCD

alternate interior angles

therefore

angle BCD = x + ECD

70°=x+50°

x=70°-50°

x= 20°
