Question

Hi guys, please help me solve this question!

Find x. (the pic given here!)​

Answer 1

Answer:

x=20

Step-by-step explanation:

here line AB || CD and line EF || CD

see here angle ABC=70 so angle BCD will also be 70............(1)(by alternate angle)

Now angle FEC=130,so angle ECD will be 50......

(2)(by co interior angles)

now using (1) and (2)

angle BCE will be angle(BCD-ECD)=70-50

=20
