according to linear angle sum property,
(20 - x) + (y + 90) = 180° ----(1)
(x + 10) + (y + 90) = 180° ---(2)
subtract (1) and (2) , we get
(20 - x) - (x + 10) = 0
20 - x - x - 10 = 0
2x = 10 => x = 5
Answer: value of x = 5

Answer:
x = 5
y = 75
Step-by-step explanation:
see in first case
20 - x = x + 10 (vertically opposite angles)
=> 20 - 10 = x + x
=> 10 = 2x
=> x = 5
now we know that x = 5
now (x + 10)+(y + 90) = 180(adjacent angle making a straight line
and x = 5
=> 5 + 10 + 90 + y = 180
=>105 + y = 180
=> y = 180 - 105
=> y = 75
