x  = 15°

∠ 1   = 45°

Step-by-step explanation:

Here Given: m is parallel to n.

Now here:

135° + (2 x+ 15)° = 180°  ( LINEAR PAIR)

Solving this for the value pf x, we get:

150 + 2 x  = 180

or, 2 x  = 180 - 150 =30

or, x = 30/2  = 15

⇒ x  = 15°

Now, as m is PARALLEL to n.

⇒ ∠ 1  =  (2 x+ 15)°  ( PAIR OF ALTERNATE ANGLES)

Putting the value of x=  15 in  (2 x+ 15)° , we get:

∠ 1  = 2(15) +  15 =  45°

or, ∠ 1   = 45°
