Question

in the given figure ab is parallel to CD is parallel to EF find the value of x​

Answer 1

Step-by-step explanation:

Given: AB ll CD ll EF

To find: value of x

Solution : CD ll EF

angle FEC + angle DCE = 180(co interior angles)

Hence angle DCE = 50

angle ABC = 70

angle BCD = 70(alternate interior angles)

angle BCD - angle DCE = x

x = 20
