Answer 1

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

Answer 2

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!!
