Question

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

Answer 1

Answer:

a= 40° ,b= 100°

Step-by-step explanation:

as pllq,

2a = 80° ( corresponding angles)

a = 80/2

= 40°

p is a line,

2a + x = 180

80 +x. = 180

x = 100

x = b ( alternate interior angles)

b= 100°

Answer 2

Answer:

Step-by-step explanation:

Ans : ∠a = 80° (corresponding angle)

∠b = 180° - 80° (co-interior angle)

∠b = 100°
