Question

Lines m and n are parallel. The measure of angle 6 is 55°.

What is the measure of angle 1?




35°


55°


125°


155°

Answer 1

Answer:155

Explanation:

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

Firstly angle 6 and 2 are equal because of corresponding angles

so 6 = 2

Now angle 1 + 2 = 180 ( linear pair)

angle 1 = 180 - 55

1 = 125
