Question

In the following figures (i) to (vi), a pair of parallel lines are cut by a transversal. Find the size of each lettered angle

Answer 1

I) x=60 degree as vertically opposite angle
y=x so y=60
z=128 degree
2)
q=135 degree vertically opposite angle
p=180-135=45
3)
a=70
b=110
4)
x=180-128=52
y=52
z=128
5)
a=180-75=105
b=180-105=75
c=75
d=105
6)
q=180-62=118
p=62
r=118
s=62
that's all thx

Answer 2

i)x=60 opposite angles are equal
  y= 60

ii)q = 45
   p = 135

iii) a=70
     b=110

iv)x=52
    y=52
    z=128

v)b=75
   c=75
   a=105
   d=105

vi)p=62
    s=62
    q=118
     r=118
