Question

In fig. shown lines l and m are parallel to each other and line p is the

transversal. Find the measures of angles ∠a and ∠b.​

Answer 1

Answer:

Angle a= (180-140) linear pair

= 40degree

angle a = b (alternate interior angles)

angle b = 40 degree

Answer 2

Answer:

Angle A = 40°

Angle B = 40°

Step-by-step explanation:

On line l, 140°+a= 180° (Linear Pair)

Therefore, a=180°-140°

Therefore, a = 40°

Angle B = 40° (Alternate Interior Angles)

Therefore, l and m are parellel to each other and p is a transversal.
