Answer 1

$\fbox {\bold {ANSWER}}$

If lines l and m are parallel, then

T and l will be two intersecting lines.

Angle BAC = 50° [ Vertically opposite angles ]

Similarly,

Angles ABC = 55° [ Alternate interior angles ]

Now, applying Angles sum property -

50° + 55 ° + angle ACB = 180°

x = 180° - 105°

x = 75°

So, correct option is ( 75° ).
