Question

PLEASE ANSWER!!!!
VERY URGENT ​

Answer 1

$\bf{Hello!}$

From the figure

When AB // DE and BC is the transversal,

Angle x = 80°

[Because they are parallel and x and angle ABC become corresponding angles]

When BC //EF and DE is the transversal,

Angle x = Angle DEF

[Because they are also corresponding angles]

Therefore, Angle DEF = 80°

Have a good evening!

Answer 2

Answer:

∠DEF=80°

Step-by-step explanation:

∠DEF=∠ABC= Interior Alternate Angles
