Question

please answer the questions given in the photo ​

Answer 1

Answer:

extend DC TO F

NOW ANGLE ECF=180-35=145

since, angle ECF=145°

AND ANGLE CEF=145°

SO CD|| EF(alternate interior angles)

now, angle ABC =ANGLE BCD

SO AB||CD

NOW,

AB||CD||EF

SO AB || EF

Answer 2

Answer:anleBCD=35+30=65

angleABC=65
