Answer 1

Step-by-step explanation:

a-b=80°

a=b+80° –1

and we know that a+b=180° –2 [Linear Pair]

from equations 1 and 2 we can derive that

a+b =180°

b+80° + b =180° [substituting a=b+180°]

2b+80°=180°

2b=180°- 80°

2b= 100°

b =100/2°

b = 50°

Since value of b =50°

therefore

a+b=180°

a+50=180

a=180-50

a=130°

therefore the value of a=130° and b=50°
