ANSWER
As per diagram,
l∣∣m∣∣n and p is transversal.
We know that 60
o
and ∠4 angles on a straight line.
60+∠4=180
o
∴∠4=120
o
We know that corresponding angle are equal
∠1=∠4 [ ∵ l∣∣m and p is transversal ]
∠1=∠2 [ ∵ m∣∣n and p is transversal ]
=> ∠1=∠4=120
o
[ ∵ ∠4=120
o
]
∠1=∠2=∠4=120
o
We know that vertically opposite angles are equal.
∠3=∠2
=> ∠3=120
o
[ ∵ ∠4=120
o
]
∴∠1=∠2=∠3=∠4=120
o

Step-by-step explanation:
angle X =45 ( corresponding angle )
angle X = 45
50+45 + Z =180 ( liner pair )
95 + Z = 180
Z = 180 - 95 = 85
According to Question ( A.T.Q )
X + Y
85 +45 = 130 ( value of X )
85 + 50 = 135 ( value of Y )
X + Y = 130 +135 = 265
Answer = 265
