Answer:
X=85, y=55
Step-by-step explanation:
Given that, x, y and 40° are the angles of a triangle.
x + y + 40° = 180° [since, the sum of all the angles of a triangle is 180°]
Hence, the required values of x and y are 85° and 55°, respectively.

Step-by-step explanation:
x+y+40=180
x+y=180-40
x+y=140
x=140-y -----(1)
x-y=30
140-y-y=30
140-2y=30
-2y=30-140
-2y=-110
2y=110
y=55
Put y=55 in eq (1)
x=140-55
x=85
