Answer:
Considering line AB || EF angle x and z are interior alternate angles and hence they are congruent
Therefore; angle x is congruent to angle z
Therefore ratio of y:x will also be the same to y:z i.e 3:7
so..... Let the common ratio be a
so y=3a and z=7a
3a+ 7a=180.....(consecutive interior angles are supplementary)
10a=180
a=18
y=3×18=54
x=7×18=126
