Question

Lines m and n are parallel.

What is angle 1?
35 degrees
50 degrees
55 degrees
75 degrees

Answer 1

The answer would be 55, because they are parallel lines. If the angles differed even by 1°, eventually the lines would meet, therefore they would not be parallel.

Answer 2

Answer: 55 degrees.

Explanation:

We know that lines M and N are parallel.

The angle 1, is the angle in the first quadrant formed by the intersection of lines k and n.

we can see that in the quadrant 1 of the intersection between lines k and m, the angle is 55°

Then knowing that n and m are parallel, the angles in each quadrant of the intersection km must coincide with the angles in the corresponding quadrants of kn.

Then we have that the angle 1 must be equal to 55°
