Answer:
4) 80,30,70
Step-by-step explanation:
the sum of angles is 110 which is 80+30=110
and difference is 50 which is 80-30=50
and 80+30+70=180 which satisfies the sum of triangle

ATQ,
Case I
x + y = 110° -----(1)
Case II
x - y = 50° -----(2)
On adding (1) & (2)
x + y + x - y = 110+50
2x = 160
x = 160/2
x = 80°
Put value of x in (2)
80 - y = 50
80-50 = y
30°= y
or
y = 30°
Now in ∆ABC
x + y + z = 180° ( using Angle sum property)
80°+30°+ z = 180°
z = 180°-110°
z = 70°
Hence, (4) 80°,30°,70° option is correct!!
