Answer 1

Answer:

x=30 using alt int angle property

in triangle ABD

x+y+80=180 [asp]

x+y=100

30+y=100

y=70

[70-30]+30+z =180 [asp]

40+30+z=180

z=180-70=110

hope u found this answer helpful

if yes plz follow me

Answer 2

Answer:

x=30 y=70

Step-by-step explanation:

AB||CD

therefore x=30 (alt angle )

we know that sum of all angle of a triangle is 180

in triangle ABD

so,80+x+y =180

80 + 30 + y = 180

110 + y = 180

y = 180 - 110

y = 70

also , z + 30 + y - 30 =180

z + 30 + 70 -30 = 180

z + 100 - 30 = 180

z + 70 = 180

z = 110

Hope its helpful for u
