Question

1. If line m | line n and angle6 measures 55 degrees , what is the measure of angle1

Answer 1

m<1 = 125°

Explanation:

Given that line m is parallel to line n, therefore:

m<2 = m<6 (corresponding angles theorem)

m<2 = 55°

Therefore,

m<1 = 180° - m<2 (linear pair)

m<1 = 180° - 55°

m<1 = 125°
