Question

In the figure If line l parallel line m and line n is their transversal then find b​

Answer 1

Answer:

a=75°

so b=(180°-75°)

=105°

Answer 2

Answer:

Angle b=75°

Step-by-step explanation:

Line l is parallel to line m and line n is the transversal

Angle a=75°.....(corresponding angles)

Angle a + Angle b=180°....(Angles in a linear pair)

But Angle a=75°,

75+ Angle b=180

Therefore Angle b=180-75 i.e 105°
