Question

find the values of unknowns x y z if ABCD is a parallelogram​

Answer 1

Answer:105o=x

Step-by-step explanation:

x= 105°

y= 105°

z= 75°

Step-by-step explanation:

y=angle ABF– angle ABC =180°–75°=105°

AB||DC & bisected by BG , therefore

angle ABC= angle DCG= z =75° [similar angles]

And,

angle CBF= angle BCD

=> y=BCD=105°

BG||DE. and bisector CH; herefore,

angle BCD= angle ADH [similar angles]

=> 105°= x

Answer 2

Answer:

75°+y=180

y=180°-75°

y=105

z=x=75°
