Answer:
The value of angles are ∠ p is 60° , ∠ r is 60° , ∠ s is 120° , ∠ t = 60°
Step-by-step explanation:
Given as :
Lines l and m are parallel to each other
So, from the condition of parallel lines
∠ s = 120° as both are alternate exterior angles
So , ∠ r = 180° - 120°
I.e ∠ r = 60°
Now, again
∠ r = ∠ p as both are corresponding angles
I,e, ∠ p = 60°
Again ,
∠ p + ∠ t = 120° as exterior angles are sum of opposite angles
so , ∠ t = 120° - ∠ p
Or, ∠ t = 120° - 60°
I,e ∠ t = 60°
Hence The value of angles are ∠ p is 60° , ∠ r is 60° , ∠ s is 120° , ∠ t = 60° Answer
