Question

/ A and / B are .... angle if /A+/B = 180 a opposite b correspondind c alternate d linearpair​

Answer 1

Answer:

a + 140° = 180° (Linear pair)

a = 180° - 140° = 40°

But b = a (Alternate angles)

= 40°

a = 40°, b = 40°

(ii) l II m and p intersects them

b + 60° = 180°

b = 180° - 60° = 120°

And a = 60° (Corresponding angle)

a = 60°, b = 120°
