plz help this question plz plz​

Answer 1

Answer:

Step-by-step explanation:

y= 180-110 (Linear pair)

y= 70degree

70+55+x=180 (Angle sum property)

125+x=180

x= 180-125

x= 55degree

(ii) x=75degree (vertically opposite angles)

45+ 75+ y= 180 (Angle sum property)

120+y= 180

y= 180-120

y= 60 degree

(iii) x= 60degree (vertically opposite angles)

40+60+y= 180 (Angle sum property)

100+y=180

y= 180-100

y= 80degree

(iv) y=x (Vertically opposite angles)

[All the exterior angles are vertically opposite thus all the interior angels are x]

x+x+x=180

(Angle sum property)

3x=180

x=180/3

x=60degree

(v) y= 70degree (Vertically opposite angles)

70+x+x=180 (Angle sum property)

70+2x=180

2x= 180-70

2x=110

x=110/2

x= 55degree

(vi) y=x (Corresponding angles)

54+46+x= 180 (Angle sum property)

100+x=180

x= 180-100

x=80degree
