in fig 8.35 , AB||CD. if angle c =50° and angle m=115°, find all other angle
Answers
Answer:
angle c=angle a=angle e=angle g=50°
angle m=angle o=angle k=angle i=115°
angle m+angle n=180°
115°+ angle n=180°
angle n =angle p=angle l=angle j=65°
angle a+ angle b=180°
50°+angle b=180°
angle b=angle d=angle f=angle h=130°
Answer:
given - angle c = 50° , angle m =115°
to find - angle a , angle b , angle d , angle e , angle f , angle g , angle h , angle i , angle j, angle k , angle l , angle n , angle o , angle p .
line AB || line CD
line ( Y ) passing through line AB and line CD
angle a = angle c
( vertically opposite angles )
angle a = 50°
angle b + angle c = 180°
( angles in a linear pair )
180° = 50° + angle b
180° - 50 ° = angle b
angle b = 130 °
angle d = angle b
( vertically opposite angles )
angle d = 130 °
angle e = angle a
(corresponding angles )
angle e = 50°
angle f = angle b
( corresponding angles )
angle f = 130°
angle g = angle c
( corresponding angles)
angle g = 50°
angle h = angle d
(corresponding angles )
angle h = 130°
line AB || line CD
line ( Z) passing through line AB and line CD
angle m + angle n = 180°
(angles in a linear pair )
115° + angle n = 180°
180 °- 115° = 65 °
angle n = 65°
angle o = angle m
( vertically opposite angles)
angle o= 115°
angle p = angle n
( vertically opposite angles)
angle p = 65°
angle i = angle m
( corresponding angles)
angle i = 115°
angle j = angle n
( corresponding angles)
angle j = 65°
angle k = angle i
( vertically opposite angles)
angle k = 115°
angle l = angle j
( vertically opposite angles)
angle l = 65°
hope it helps you.....
