Question

find the value of x in each of the following figure if line l is parallel to line m​

Answer 1

Answer:

2x+x=180 (interior angles)

3x=180

x=60

Answer 2

I is parallel to M.

so, x & 2x are interior angles.

‍‍sum of interior angles are always 180 degrees.

x+2x = 180 degrees

or, 1x+2x=180 degrees

or, 3x=180 degrees

or, x= (180/3) degrees=60 degrees

x = 60 degrees.
