Question

please answer this question it is very important and urgent​

Answer 1

Answer:

a=110°

b=70°

Step-by-step explanation:

sum of all angles of a triangle=180°

50°+60°+b=180°

110°+b=180°

b=180°-110°

b=70°

a+b=180°(since linear pair)

a+70°=180°

a=180-70°

a=110°

Answer 2

We know that sum of a triangle is 180 degree
So,
50 + 60 + b = 180
110 + b = 180
b = 180 - 110
b = 70

Hence b is 70 degree
