Question

1) Find the value of a and b , given that p||q and r||s​

Answer 1

Answer:

Here,

value of b is 180-80 =100.[linear pair]

And value of a is 2a =80

Therefore, a=80/2=40.

Answer 2

Answer:

a=40° and b=100°

Step-by-step explanation:

Given p||q and r||s

2a=80° (corresponding angles)

a=80/2

a=40°

b=180°-80°( Adjacent angles formed by parallel lines)

b=100°

Therefore, Values of a and b are 40° and 100°
