Answer:

Step-by-step explanation:

let the angle be a.

ratio is given,

∠ihd=∠z                                                                (by corresponding ∠)

∠y+∠z= 180°                                            

3a+7a=180

a=20

∠y=3a=60

∠z=7a=140

∠z=∠x                                                                      (alt. interor angle)

∠x=140
