Question :
In the given figure PQ || RS, and l is Transversal, then what will be the Value of x.
To Find :
- we need to find the value of x
Given :
- PQ || RS and l is Transversal.
We know that,
As it is given in the Question that PQ is parellel to RS and l is Transversal , Then pair of Alternate angles are equal to each other.
So,
⇛∠2x + 30 = ∠x + 70
⇛ 2x - x = 70 - 30
⇛ x = 40
Hence,
- Value of x = 40
And the given angles are :-
⇛2x + 30
⇛2 × 40 + 30
⇛80 + 30
⇛110°
And,
⇛ x + 70
⇛40 + 70
⇛110°

Answer:
Step-by-step explanation:
It is given that ∠
From the figure we know that ∠1 and ∠2 form a linear pair of angles
So it can be written as
∠
By substituting the values
On further calculation
By subtraction
From the figure we know that ∠1 and ∠3 are vertically opposite angles
So we get
From the figure we know that ∠2 and ∠4 are vertically opposite angles
So we get
∠1 = ∠5 = 120o
It is given that, l || m and t is a transversal
So the corresponding angles according to the figure is written as
hope it helps
