Question

if lines m and n are parallel, and < 1 measures 125°, which is the measure of < 2?

a. 25°

b. 40°

c. 55°

d. 150°

Answer 1

C. 55 degrees.
Solving: Since it’s on the same line, you can do 180 - 125 to solve for.

Answer 2

Answer: 55°

Step-by-step explanation:

Line n is irrelevant.

Angle 1 plus angle 2 is 180° because line m is a straight line

180 - 125 is 55
