Question

Find x...................

Answer 1

Answer:

120 degree

Step-by-step explanation:

make point of intersection of CH and AD as O

ABO=150+x(linear pair)

     x=30

180=BAO+ABO+BOA(ANGLE SUM PROP.)

180=30+30+BOA

180=60+BOA

180-60=BOA

BOA=120

HOD=120(VERTICALLY OPP. ANGLES)

X=HOD(ALTERNATE INTERIOR ANGLES)

∴x=120 degree
