Question

2. In the given figure some values of angles are given. Find the values of x and y and state whether line MN is parallel to line PQ with reason. (2 marks) BA SO 다 M N 17 130​

Answer 1

Answer:

sum of the interior angles on the same side of transversal is 180

∘

b+52

∘

=180

∘

⇒b=180

∘

−52

∘

=128

∘

And a=52

∘

∴a=52

∘

,b=128

∘

Answer 2

Step-by-step explanation:

As per diagram l∣∣m and n transversal.

We know that vertically opposite angles are equal

a=110

o

----(1)

d=85

o

----(2)

We also know that corresponding angles are equal.

a=b

d=c

=>a=b=110

o

[ from (1)]

=>d=c=85

o

[ from (2)]
